How Many Americans Does It Take to Elect a President?

Or how I learned to start worrying and hate the electoral college
2016 ballot - Shamelessly ripped from somewhere on the internet

In 2016, the candidate who won the most votes* lost the election, which has led a number of consternated people to calculate the percentage of American voters who voted for her rival. There are a couple of different ways to do this math:

  1. The number of voters who voted for each candidate divided by the total number of voters who voted in the 2016 election.
  2. The number of voters who voted for each candidate divided by the total number of registered voters.
  3. The number of voters who voted for each candidate divided by the total number of eligible* voting age citizens in the United States.

Each of these measures a slightly different thing. 1 measures the strict election results without any comparison for voter turnout. 2 & 3 measure voter turnout in slightly different ways, 2 representing people who care enough to actually register. 3 provides the most contrast and insight: 25% of eligible Americans voted for the candidate who won the 2016 election.

That’s a startling number that throws a dark shadow over our elections. It means that 75% of Americans are not represented by the results of that election or the person currently holding the office of president.

This got me to thinking: How does this compare to previous elections? How systemic is this problem of voter turnout? Which president got the most (highest percentage of) Americans to vote for them?

The answer is:

  • 2016 was a (slightly below) average election.
  • The problem is incredibly systemic and long term.
  • LBJ got 37.5% of Americans to vote for him in 1964. (And here I thought it'd be FDR, but at his best in 1936 he only managed to get 34.3% of Americans to vote for him.)
  • GHW Bush only got 23.7% of Americans to vote for him.

This matters because it means that in any given presidential election, only 1/4 of America is being represented by the winner. Tyranny of the minority.

But this result makes sense because of the electoral college. Because of the winner-take-all system of allocating electoral college votes used by 48 of the States, 50% of any given state's voters are ignored by the election. If that 50% simply chooses not to vote rather than vote for a losing candidate, we wind up with 50% voter participation. The remaining 50% of voters who do participate split 50/50 based on party affiliation. The actual numbers in any given election vary but hover around 60% voter participation and 60/40 splits. 

It's also worth noting that this winner-take-all low-voter-turnout system caused by the electoral college also encourages a bipolar party system that severely limits the ability for a 3rd party candidate to make significant progress in a presidential election. 3rd party candidates are also significantly hindered by the constitutional requirement that the winner of the election must receive greater than 50% of the votes or the election goes to the House. This is why the numbers in the data all hover around 29%. A candidate has to impress roughly half of the participating voters but only 1/4 of all eligible voters in order to win because of the electoral college's impact on voter participation and election outcomes.

The takeaway from this is that any given presidential candidate only needs to impress 25% of Americans to win the election. And that's a bad thing.


* In this article I refer to Americans as voting directly for president. However, in the United States, because of the electoral college, Americans don't vote for their president. Instead, they vote for electors who then vote for the president based on rules written by the state's legislature. These electors, representatives of their state and not the people, vote for and elect the president. This is a subject of great debate, but is generally recognized as a bad idea.

* For the purposes of this article, I used VAP - Voting Age Population - because it was the statistic that was available. A more refined number, taking into account factors such as disenfranchisement, called Voting Eligible Population (VEP) exists, but the data for elections going back decades does not exist.

* The data available only took me back as far as 1932. Beyond that year, the data for the total VAP wasn't (readily) available and may not exist. My data sources include this Wikipedia article and this Encyclopaedia Britannica Online article.
