Vice President Kamala Harris is the most likely replacement for President Joe Biden if he drops his 2024 presidential bid—which some top Democrats think could happen as soon as this weekend—and she is performing about the same as Biden in head-to-head polls with Trump.

A flurry of polls conducted in the wake of the June 27 presidential debate showed Harris performing roughly the same as Biden against Trump (who has been leading the president by a slim margin for months), and more recent polls after the attempted assassination of Trump show similar trends.

Harris has also polled better than other Democrats commonly floated as replacement candidates to Biden, but the polls didn’t factor in how months of campaigning could change voters’ perceptions of many of the lesser-known candidates that don’t have the benefit of national name recognition like Harris does.

A YouGov poll (margin of error 3.1) conducted July 13 - 16 and released Thursday found Biden would lose to Trump 41% to 43%, while Harris would perform slightly worse, losing to Trump 39% to 44%.
