Tracking Poll Finds Race a Dead Heat

The Washington Post-ABC News tracking poll shows Hillary Clinton barely edging Donald Trump in the presidential race, 46% to 45%.

Key finding: “Greater Republican unity has buoyed Trump’s rising support, which has wavered throughout the year. Trump’s 87-percent support among self-identified Republicans, ticking up from 83 percent last week nearly match Clinton’s 88-percent support among Democrats. Independents also have moved sharply in Trump’s direction, from favoring Clinton by eight points one week ago to backing Trump by 19 points.”
