• Live: Kamala Harris says she is looking forward to accepting Democratic nomination

In a hypothetical head-to-head matchup, Harris and Trump were tied with 44% support each in a July 15-16 Reuters/Ipsos poll conducted immediately after the July 13 assassination attempt on Trump. Trump led Biden 43% to 41% in that same poll, though the 2 percentage point difference was not meaningful considering the poll's 3-point margin of error.

An average across recent polling reported shows Harris trailing Trump by 2 points, with 46% to 48%, the New York Times reports, though Biden trailed Trump by three points, 44% to 47%.
