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.
But, there have been a ton of polls, both nationally and in individual states, with age gaps that look very different than 2012. I could see an argument for a smaller age gap- largely due to 65+ voters trending Democratic because of a dislike of Trump not being a normal candidate and under 30 voters voting at lower rates, more for third parties, and some "Trump-Sanders" swing voters.
