Of America’s 320 million-odd residents, only about three-quarters are eligible to vote (mostly because they’re over the age of 18). Of the group that could vote in the presidential election, the U.S. Election Project’s Michael McDonald estimates that about 58.1 percent did — meaning that 41.9 percent of eligible Americans didn’t vote last week.
Using the most recent national splits from the Cook Political Report’s Dave Wasserman, that means that Donald Trump was elected president with the support of fewer than 1 in 5 Americans.
