Fifty-nine percent of likely voters, moreover, reject Trump’s suggestion that the election is rigged in Clinton’s favor, and more, 65 percent, disapprove of his refusal to say whether he’d accept a Clinton victory as legitimate. Most strongly disapprove, a relatively rare result.

All told, Clinton leads Trump by 12 percentage points among likely voters, 50 to 38 percent, in the national survey, her highest support and his lowest to date in ABC News and ABC News/Washington Post polls. Gary Johnson has 5 percent support, Jill Stein 2 percent.

The results mark a dramatic shift from Clinton’s +4 points in the last ABC/Post poll Oct. 13. That survey was conducted after disclosure of an 11-year-old videotape in which Trump crudely described his sexual advances toward women, but before the events that have followed: A series of women saying he sexually assaulted them, which Trump has denied; his continued refusal to say whether he’d accept the election’s legitimacy; and the final debate, which likely voters by 52-29 percent say Clinton won.
