Roughly 43 percent of eligible voters didn’t bother filling out a ballot this year, according to turnout estimates from the U.S. Elections Project. To look at it another way, the people who could have voted but chose not to vastly outnumbered those who cast a vote for Clinton, Trump or a third-party candidate. The U.S. Elections Project, run by a political scientist at the University of Florida, estimates that there are about 251 million voting-age people in the U.S. But not all of them are eligible to vote: some are non-citizens living in the U.S., while several million more can’t legally vote because they’re in prison, on parole, or have a past felony conviction in states where that’s a barrier to voting. Subtract all those people and you’ve got about 232 million people potentially eligible to cast a vote this fall. But only about 132 million of them did, give or take the one or two million votes that have yet to be officially certified. That means that 100 million people who have the legal right to vote simply decided it wasn’t worth the hassle this year.
