By the numbers: The Trump hot-mic tape pushed wavering voters away -- but brought his base even closer

And that said, there were big shifts to Clinton between the two Fox polls were among women broadly and among college-educated whites. One reason women moved more to Clinton than did men is that white men without college degrees were pushed even more toward the Republican nominee relative to last week.

Why? It’s a good question. Trump’s strategy of late has been consistently to double-down on the core base of his support. During the debate, he plucked every past possible Clinton conspiracy theory from the Breitbart archives and dropped them at the audience’s feet. That’s one possible reason that white men without degrees — the heart of his support — may have embraced him more tightly.

Clinton’s favorability went up a bit over the week, particularly among white men with college degrees. Trump’s sank, especially among those whites with degrees broadly.
