One in three Democrats think President Joe Biden should withdraw from running for a second term, after last week’s disastrous phone call with Donald Trump. But no Democrat-elect would fare better than Biden in a hypothetical showdown with Trump on Nov. 5, according to a Reuters/Ipsos poll.

The two-day poll found both Trump, 78, and Biden, 81, securing the support of 40 percent of registered voters, meaning the Democratic president did not lose ground after the debate.

Of the top Democrats, in a hypothetical “battle” with Trump, only Michelle Obama, the wife of former President Barack Obama, would do better than Biden: she would garner 50% to Trump’s 39% . Michelle Obama has stated many times that she does not intend to run for the presidency of the United States.

32% of Democratic voters said Biden should retire after he failed to fend off Trump’s attacks and numerous false claims on the phone call.

Biden has vowed to continue his campaign. If he were to leave, the Democrats who would likely replace him would perform similarly or worse than him against Trump, according to the poll. For example, Vice President Kamala Harris is one point behind Trump (42% vs. 43%), a margin of error. California Gov. Gavin Newsom, the party’s rising star, would fare marginally worse, with 39% to Trump’s 42%.
