The poll finds Democratic frontrunner Hillary Clinton ahead of Trump by just 6 points, a dramatic tightening since July. Trump is the one of three Republican candidates who have been matched against Clinton multiple times in CNN/ORC polling to significantly whittle the gap between himself and the Democratic frontrunner. He trailed Clinton by 16 points in a July poll, and narrowed that gap by boosting his standing among Republicans and Republican-leaning independents (from 67% support in July to 79% now), men (from 46% in July to 53% now) and white voters (from 50% to 55%).
But Clinton still holds the cards overall in the race for the White House, leading four Republican contenders: She tops Trump and Wisconsin Gov. Scott Walker by 6 points each among registered voters, former Florida Gov. Jeb Bush by 9 points, and businesswoman Carly Fiorina by 10 points.
