Polls Underestimated Trump’s Support

Vox: “The polls were quite close in their forecast for Clinton’s support. Clinton was expected to get 47 percent of the vote; she’s got 47.7 percent so far. On average, the polls understated her state-level support by about a percentage point.”

“Trump, however, was expected to get 44 percent of the vote, and he now has 47.5 percent; the polls undershot his support considerably… As the undecided made up their minds, and as third-party supporters moved toward the major party candidates (as they tend to do in a campaign’s final days), it looks like Trump picked up almost all of them.”
