This is factually inaccurate, unless you want to go all MoE or unless you're talking about 2008.
"Clinton has a 21-point lead over Trump among women, while Trump has a five-point edge among men. Along educational lines, white voters are sharply divided. Trump carries voters without college degrees by 57 to 33 percent; Clinton wins those with college degrees by 52 to 37 percent."
According to Teixeira, the split among white working-class/college-educated voters in 2012 was 44/56. It's likely that the latter will increase in size at expense of the former, but let's just assume they hold steady and then plug in those numbers above:
Share of White Vote:Clinton: (52*0.56)+(33*0.44) = 43.6%Trump: (37*0.56)+(57*0.44) = 45.8%Clinton's winning 44% of the white vote in comparison to Trump's 46% in this poll. That's a far cry from Obama 2012 with 39-40% and Romney with 59-60%. Getting even close to that (
with 10% of the electorate undecided, no less) potentially puts both the House and the Senate in danger of falling, as well as may open up potential pathways down the Atlantic and in the Southwest.
