Hillary Clinton has opened up a 12-point advantage over Donald Trump following their final debate last week and has reached the critical 50-percent mark, according to a new poll released Sunday.

Clinton’s 50-percent-to-38-percent lead over Trump in the first ABC News tracking poll, which is comprised of interviews conducted Thursday through Saturday, represents a swing from an ABC News/Washington Post poll following the second Clinton-Trump debate, which showed Clinton ahead by just four points, 47 percent to 43 percent.
