The previous ABC/Post poll found a sharp 12-point decline in enthusiasm for Trump among his supporters, almost exclusively among those who’d preferred a different GOP nominee. Intended participation now has followed: The share of registered Republicans who are likely to vote is down 7 points since mid-October.

Vote preference results among some groups also are striking. Among them:

• Clinton leads Trump by 20 percentage points among women, 55-35 percent. She’s gained 12 points (and Trump’s lost 16) from mid-October among non-college-educated white women, some of whom initially seemed to rally to Trump after disclosure of the videotape.

• Clinton has doubled her lead to 32 points, 62-30 percent, among college-educated white women, a group that’s particularly critical of his response to questions about his sexual conduct. (Seventy-six percent disapprove, 67 percent strongly.)

• That said, Clinton’s also ahead numerically (albeit not significantly) among men, 44-41 percent, a first in ABC News and ABC/Post polling.
