The magnate treasures a vote intention of 46%, versus 45% of Clinton.
The Republican was quick to react to the new data.
"Wow, now we lead the survey @ ABC /
@Washingtonpost by 46 to 45. We gained 12 points, most before the scandal Hillary" Trump wrote, referring to the scandal that erupted last week when the FBI reopened the investigation Clinton emails sent from a private server when he was secretary of state.
The Washington Post noted that the poll has a margin of error of 2.5 percentage points, but also revealed the true collapse of enthusiasm shown Clinton voters by the candidate itself.
According to the survey, enthusiasm for the former Secretary of State fell seven points as a result of the scandal.
In this regard, 53% of voters say Trump is "very excited" with her candidacy, against only 43% among voters of Clinton.
Just a week ago, that "enthusiasm" among Clinton voters was 51%, so that the survey detected a clear cooling among his followers.
The newspaper recalled that, in the absence of a week to the presidential elections of 2012, enthusiasm among voters of Obama was 64% against 61% of his opponent Mitt Romney.
FBI Director James Comey announced last Friday the discovery of new emails that transited a private server that Clinton used, contrary to the rules of the State Department.
The Washington Post also reported Tuesday that Clinton has a lead of 54% to 41% on Trump among voters who voted early, but Trump has a lead of 50% to 39% among those who said they were confident that will vote on 8 November.
This new survey was conducted between 27 and 30 October.
