Ahead of Monday's first presidential debate of the 2016 campaign, a new poll shows Democrat Hillary Clinton and Republican Donald Trump in a "virtual dead heat."
In the Washington Post/ABC News poll, Clinton garnered support from 46 percent of likely voters compared to Trump's 44 percent. Libertarian Gary Johnson and the Green Party's Jill Stein received 5 percent and 1 percent of likely voters' support, respectively.
Clinton and Trump each had 41 percent support from registered voters, followed by Johnson with 7 percent and Stein with 5 percent.
The poll also tested a head-to-head matchup between Clinton and Trump. In that scenario, Clinton secured support from 49 percent of likely voters compared to Trump's 47 percent. Among registered voters, Clinton and Trump are each polling at 46 percent.
The results are within the poll's margin of error.
The telephone poll of 1,001 adults, conducted September 19 through September 22, has an overall margin of error of plus or minus 3.5 percentage points. The poll included samples of 834 registered and 651 likely voters, which had margins of error of plus or minus 4 points and 4.5 points, respectively.
Clinton and Trump will square off tonight during the first presidential debate at Hofstra University in Hempstead, New York. The debate starts at 8 p.m. CT.
