The opinion poll conducted on Monday and Tuesday found that 43% of registered voters said they would support Biden in the Nov. 3 presidential election, while 41% said they would back Trump. That makes the contest essentially a toss-up, as the results are within the poll’s credibility interval.

Biden led by 6 percentage points in a similar poll last week and by 8 points in a poll that ran April 15 to 21…

Some of Biden’s most dominant recent headlines focused on a former U.S. Senate aide’s allegation that he sexually assaulted her in 1993. Biden said last week the alleged assault “never happened” and asked the Senate to make public any documents related to the accusation by Tara Reade, who worked as a staff assistant in Biden’s Senate office from December 1992 to August 1993.

The political impact of the situation was not yet clear in the Reuters/Ipsos poll, which showed 53% of the American public said they were “somewhat” or “very” familiar with Reade’s allegation.
