As I detail here, the Electoral College (“EC”), not direct popular vote, determines who wins American presidential elections. Since 1856, the first presidential election in which the two major candidates were a Democrat (James Buchanan) and Republican (John C. Fremont), there were four presidential elections in which one candidate won the EC while another candidate won the popular vote; in all four elections—1876, 1888, 2000, 2016—the Republican won the EC and, thus, the presidency.
Those elections—just four out of 41 (10%)—could be considered flukes, were it not for the fact Republicans maintain a clear, quantifiable advantage in the EC.
One way to think about this is to consider a presidential election in which the two major-party candidates receive exactly the same number of popular votes. Put another way, this is a situation where the difference between the Democratic percentage of the popular vote and the Republican percentage of the popular vote equals 0.0%.
If there was no partisan advantage in the EC, we would expect both candidates to receive 269 electoral votes (“EV”), exactly half of the 538 available to them. Or, at least, a number very close to 269, allowing for third-party candidacies and “faithless” electors who vote for someone other than the plurality winner of their state.
Table 1 lists the winner, political party, popular vote margin (Democratic % – Republican %) and number of EV won by the winning candidate for the 17 presidential elections from 1952 through 2016. I chose 1952 because it was the first presidential election to feature television commercials by the major candidates and televised nomination conventions. It is also the first election to show cracks in the previously solid Democratic south: Republican Dwight D. Eisenhower won Florida, Tennessee, Texas and Virginia in 1952, adding Kentucky and Louisiana in 1956. As usual, all elections data come from Dave Leip’s indispensable Atlas of U.S. Presidential Elections.
Table 1: Winning Presidential Party, Margin of Victory (Dem % – GOP %) and Electoral Votes Won: 1952-2016
|Year||Electoral College Winner||Party||Margin||EV|
Republicans won 10 of these elections, by an average margin of 8.6% in the popular vote and 393.9 EV; this includes 2000 and 2016, when Democrats Al Gore and Hillary Clinton, respectively, won the popular vote but lost the EC. Democrats, meanwhile, won seven of these elections by an average margin of 7.1% and 361.7 EV.
In three elections, the Democratic and Republican percentages of the popular vote differed by less than one percentage point (“point”): 1960, when Democrat John F. Kennedy won by 0.2% with 303 EV; 1968, when Republican Richard M. Nixon won by 0.7% with 301 EV, with 13.5% and 46 EV for American Independent nominee George Wallace; and 2000, when Republican George W. Bush lost by 0.5%, but still eked out 271 EV after a controversial recount in Florida.
It is difficult to discern any sort of pattern here, other than the higher the popular vote margin, the more EV you win. Figure 1 shows this clearly.
Figure 1: Popular Vote Win Margin and Electoral Votes Won, 1952-2016
As expected, there is a strong linear association between popular vote margin and EV won—including 2000 and 2016; margin alone accounts for 86% of the variance in EV. The formula was calculated using ordinary least squares (“OLS”) regression, and it tells us the average number of EV one would expect a presidential candidate to win based upon their popular vote margin.
Thus, for every 1.0-point increase in popular vote margin (expressed as 0.01), that candidate wins an 11.1 additional EV, on average. Moreover, when the margin is 0.0 points—a popular vote tie—the winner should receive 292 EV, 23 more than the expected 269 or so. Also, to earn 270 EV, the winner would actually LOSE the popular vote by 2.0 points!
How is this possible?
Figures 2 and 3, which break down the popular vote margin-EV association by party, help to explain.
Figure 2: Popular Vote Margin and Electoral Votes Won: Democratic Presidential Candidates, 1952-2016
Figure 3: Popular Vote Margin and Electoral Votes Won: Republican Presidential Candidates, 1952-2016
For both major political parties, every 1.0-point in popular vote margin increases EV earned by an average of 12.3. And in both models, popular vote margin alone accounts for 92% of variance in EV; these two variables are VERY strongly linearly associated.
However, it is where the fitted line crosses the Y axis that makes all the difference—this is the expected EV won by each political party in the event of a tied popular vote. For Democrats, a tie equates to only 251.0 EV, on average, 19 fewer than needed to win the presidency. For Republicans, however, that same tie equates to 282.7 EV, 12.7 more than needed to win the presidency. The slopes and r-squared values are identical, the Republican line is just 31.7 points higher at every value of popular vote margin.
In other words, on average, a tied total popular vote translates to a 283-251 Republican win in the Electoral College, with 4 EV going to third-party candidates or otherwise up for grabs. That translates to a 32-EV Republican advantage in the Electoral College.
Another way to measure Republican advantage is to calculate what popular vote margin a presidential candidate needs, on average, to secure 270 EV. For the Democratic presidential nominee, the formula is:
Popular Vote Margin = (270 – 251.0) / 1233.1) = = +1.5%
And for the Republican presidential nominee, the formula is:
Popular Vote Margin = (270 – 282.7) / 1230.8) = = -1.0%
That is, a Democratic presidential nominee must win the national popular vote by at least 1.5 points to secure a minimum 270 votes, while a Republican presidential nominee can do so while losing the total popular vote by 1.0 points. Third-party EV and faithless electors keep the values from being identical. Still, that translates to a 2.5-point popular vote advantage for Republicans in the Electoral College!
This is a very robust finding. For example, while the 2016 election looks like an outlier—as does, to be fair, 1980, when Republican Ronald Reagan converted a 9.7-point popular vote margin of victory into 489 EV—removing it only improves the Democratic position slightly: a tied total popular vote still gives the Republican a 279.4 to 254.1 EC victory, while only reducing the popular vote advantage to 2.1 points.
Also, starting in 1964—the first election in which Alaska, Hawaii and the District of Columbia all contributed EV—actually increases the Republican advantage. The latter nominee would win 286.4 to 248.5 if the total popular vote were tied nationally, a 37.9 EV advantage equivalent to winning Texas’ 38 EV. Moreover, since 1964, a Democrat would need to win nationally by 1.8 points, on average, to win 270 EV, while a Republican could lose by 1.3 points—a gap of 3.1 points!
My analysis of national- and state-level polling suggests 2020 Democratic presidential nominee Joseph R. Biden, Jr. currently leads Republican President Donald J. Trump by 7.5 points, up slightly from the last time I wrote about the state of the race.
Plugging 0.075 into the Democratic formula yields a projected EV total of 343.5. This is remarkably close to the 349.6 EV I estimate Biden will received based on in my model; the number increases to 352 if I simply count up the EV from states I calculate Biden has >50% chance to win.
I also assess Biden’s chances if all polls are systematically over-estimating Democratic strength by 3 points and if all polls are systematically under-estimating Democratic strength by 3 points. That is, I consider a universe in which Biden is actually ahead by 4.5 points or by 10.5 points.
Entering 0.045 into the Democratic formula yields an expected 306.5 EV—basically, the states won by Clinton in 2016 plus Michigan, Pennsylvania, Wisconsin and Florida. My estimate of Biden’s EV in this scenario is 301.7, or 308 using the states where Biden is better than even money.
Entering 0.105 into the Democratic formula yields an expected 380.5 EV—basically, the previous scenario plus Arizona, North Carolina, Ohio, Georgia and Iowa…but not Texas. The polling data, however, suggest Biden would do even better—389.6 EV, or 412 using the states where Biden is better than even money, including a 57.6% chance of winning Texas.
In other words, results from this simple one-variable model align almost exactly with the state of the race based on available polling data.
Why this is the case, however, is a far more complicated question. The most direct answer is that Democratic votes are distributed less efficiently than Republican votes across the states. Democrats routinely win large states like California, New York and Illinois—104 total EV—by double-digit margins, padding their national vote total while adding 0 EV. Republicans, by contrast, win larger states by narrower margins, as they did in 2016, and smaller states like Wyoming, Idaho and Utah by huge margins which only minimally impact their national vote total.
Put differently, the Democratic strategy to run up the popular vote paradoxically hurts them in the Electoral College, while Republican strategy to eschew large national vote totals in favor of narrower wins in key states boosts them.
On a related note, Republicans have an advantage in swing states, as my 3W-RDMdemonstrates; this is a measure of how Democratic a state votes relative to the nation. Based solely on this measure, Table 2 lists how I would anticipate the following states to vote if Biden and Trump exactly tied in the total popular vote:
Table 2: Expected 2020 vote margins in 18 key states, based on tied popular vote
|State||EV||3W-RDM||Current Biden polling|
Assuming Biden starts with 175 EV and Trump starts with 126 EV, that leaves 237 EV up for grabs. In this popular-vote-tie scenario, Biden wins 84 of those EV, though Wisconsin and New Hampshire could be looking at a recount, for 259 EV. Trump wins the remaining 153 EV, with a recount possible in Pennsylvania, for 279 EV, very close to the 283-251 EV margin estimated earlier.
But while in this scenario Biden would narrowly win states like Michigan, Colorado, Nevada, Minnesota and Virginia—Trump would be looking at far easier wins in Florida, Iowa, Ohio, North Carolina, Georgia, Arizona and, especially, Texas. This is because of the enormous gap between Pennsylvania, at 0.4 points more Republican, and Florida, at 3.4 points more Republican. While a Democrat could theoretically win 279 EV—and the White House—by winning the total popular vote by 0.4 points, s/he would have to win by at least 3.4 points nationally to have a little breathing room.
That all said, Biden’s current estimated lead of 7.5 points gets him those 308 EV relatively easily, while making him slightly favored in Arizona and North Carolina, perched on the razor’s edge in Ohio and Georgia, and pounding on the door in Iowa and Texas. A slight polling error in his favor, strong Democratic turnout/depressed Republican turnout and a decisive win among late-deciding voters, and Biden could turn 343-352 EV into 412 EV.
When you know in advance how high the mountain you need to climb is, it is far easier to prepare to climb it.
Until next time…please stay safe and healthy…

Most Americans think it is wrong that the candidate with the most popular votes can lose a presidential election.
We don’t allow this in any other election in our representative republic.
Unfair elections lead to politicians and their enablers who appreciate unfairness, which leads to more unfairness.
Now we need to support, vote for, and urge state legislators in states with the 74 more electoral votes needed, to enact the National Popular Vote bill for the 2024 election.
The bill is 73% of the way to guaranteeing the majority of Electoral College votes and the presidency to the candidate who receives the most popular votes in the country.
The bill changes state winner-take-all laws (not mentioned in the U.S. Constitution, but later enacted by 48 states), without changing anything in the Constitution, using the built-in method that the Constitution provides for states to make changes.
It requires enacting states with 270 electoral votes to award their electoral votes to the winner of the most national popular votes.
All voters would be valued equally in presidential elections, no matter where they live.
I once supported this movement.
However, I now believe NPV.com simply replaces one bad set of state laws–those mandating Electors deliver all of their votes to a state’s plurality winner–with another–ignoring duly appointed Electors.
We absolutely should choose our president through a national popular vote. The Electoral College, as I wrote in https://justbearwithme.blog/2019/03/30/an-electoral-college-education/ has been an absurd anachronism since around 1800.
For now, however, it IS in the Consitution of the United States. And I do not think we should be engaging in cute legislative “end runs” around the Constitution.
Thus, it is time for a Consitutional amendment to abolish the Electoral College once and for all. All of the efforts NPV.com has put into replacing bad laws with other bad laws should really be directed into this.
This is exactly why the amendment process was designed, to update and “fix” the Constitution as the situation warranted. Yes, the process is messy, time-consuming and expensive–but so is what NPV.com is trying to do.
But it is also the only way to fix the system properly and decisively. Get rid of Electors entirely, mooting the “faithless” Elector question. Remove state laws from the process completely–other than those involving election administration and certification.
Thank you for reading. Please come back soon for more essays.
There have been hundreds of unsuccessful proposed amendments to modify or abolish the Electoral College – more than any other subject of Constitutional reform.
To abolish the Electoral College would need a constitutional amendment, and could be stopped by states with less than 6% of the U.S. population.
Instead, state legislation, The National Popular Vote bill is 73% of the way to guaranteeing the majority of Electoral College votes and the presidency to the candidate who receives the most popular votes in the country.
The Founders created the Electoral College, but 48 states eventually enacted state winner-take-all laws.
The U.S. Constitution says “Each State shall appoint, in such Manner as the Legislature thereof may direct, a Number of Electors . . .”
The U.S. Supreme Court has repeatedly characterized the authority of the state legislatures over the manner of awarding their electoral votes as “plenary” and “exclusive.”
The normal way of changing the method of electing the President is by state legislatures with governors making changes in state law.
Historically, major changes in the method of electing the President have come about by state legislative action. For example, the people had no vote for President in most states in the nation’s first election in 1789. However, now, as a result of changes in the state laws governing the appointment of presidential electors, the people have the right to vote for presidential electors in 100% of the states.
In 1789, only 3 states used the winner-take-all method (awarding all of a state’s electoral vote to the candidate who gets the most votes in the state). However, as a result of changes in state laws, the winner-take-all method is now currently used by 48 of the 50 states.
In 1789, it was necessary to own a substantial amount of property in order to vote; however, as a result of changes in state laws, there are now no property requirements for voting in any state.
In other words, neither of the two most important features of the current system of electing the President (namely, that the voters may vote and the winner-take-all method) are in the U.S. Constitution. Neither was the choice of the Founders when they went back to their states to organize the nation’s first presidential election.
The normal process of effecting change in the method of electing the President is specified in the U.S. Constitution, namely action by the state legislatures. This is how the current system was created, and this is the built-in method that the Constitution provides for making changes. The abnormal process is to go outside the Constitution and amend it.
States can, and have, changed their method of awarding electoral votes over the years. Maine (in 1969) and Nebraska (in 1992) chose not to have winner-take-all laws
The constitutional wording does not encourage, discourage, require, or prohibit the use of any particular method for awarding a state’s electoral votes.
The Supreme Court reaffirmed the power of states over their electoral votes.
The ruling says electors must abide by state laws and that such laws are constitutional.
The decision held that the power of the legislature under Article II, Section 1 of the Constitution is “far reaching” and it conveys the “the broadest power of determination over who becomes an elector.” This is consistent with 130 years of Supreme Court jurisprudence.
Now 48 states have winner-take-all state laws for awarding electoral votes to the statewide winner.
2 award one electoral vote to the winner of each congressional district, and two electoral votes statewide.
Neither method is mentioned in the U.S. Constitution.
All of the electors from the National Popular Vote enacting states would be required to vote for the winner of the most national popular votes.
My husband has tried to get me to accept EV but I just can’t. It really irritates me…lol
The Electoral College should have been repealed in 1800!
