WORCESTER, Mass. – President Joe Biden and former president Donald Trump were back on the campaign trail Friday, hours after taking the stage for the first presidential debate of this election season the night prior.

There were moments of bickering and personal attacks. Both campaigns put out statements saying their candidate won.

But Friday, Biden appeared to acknowledge the criticism of his delivery, saying, he "doesn't debate as well as he used to.”

Political analyst and Boston University Professor Matt Motta said he believes it may be time to remove the president from the ticket.

Motta said Biden and Trump were locked in a close race prior to Thursday night and due to geographic imbalances in the apportionment of electors in the Electoral College, Biden needs to be up by a few percentage points to win the race. That means that on Thursday night, he needed to not just maintain support, but gain support.

“It just doesn’t seem that clear to me that anybody who watched the debate last night would be more likely to vote for the president, rather than less,” Motta said. “It does seem to make sense to me that a replacement at the top of the ticket could be warranted here.”

Meanwhile, Motta said while Trump was more poised, there was still a lot of bickering between the two and not a lot of discussion on policy.

Motta said it’s become par for the course to put aside discussion of issues in favor of personal attacks.

“When they debate like this one, it’s not all that surprising to see these two men going after one another as people on a highly personal level because is the type of discourse that tends to resonate with voters,” said Motta. “It's pretty rare that debates have an impact on vote choice, at least in their immediate aftermath."
