The crosstabs have Trump winning voters under 30(!):
Trump 48%
Clinton 39%
Johnson 8%
Stein 4%
They’ve also got Trump with 33% of blacks and 52% of Hispanics. In fact, while they have him over 50% among Hispanics, he’s under 50% among whites.
I really do wonder if 1) pollsters are vastly underestimating Latino turnout and 2) oversampling Trump's support among this group.
FWIW this happened with Trump analogue, David Duke, in his gubernatorial run in the 90s. The polls overstated Duke's position and he lost by more than predicted because the polls bungled reaching out to blacks.
