Democratic Rep. Mike Quigley is skeptical that President Joe Biden’s startling debate performance was just a bad night, and he urged the president to consider how his place on the ticket impacts the fate of Democrats in the Congress.

“We have to be honest with ourselves that it wasn’t just a horrible night,” Quigley told CNN host Kasie Hunt on Tuesday. “But I won’t go beyond that out of my respect and understanding for President Joe Biden, a very proud person who has served us extraordinarily for 50 years. I just want him to appreciate at this time just how much this impacts not just his race but all the other races coming in November.”

Earlier in the interview, Quigley said Biden “has to be honest with himself” because his decision, and its results on how Democrats perform down-ballot, “will have implications for decades to come.”

In the days since Biden’s disastrous debate performance Thursday, where he was at times unable to string together complete sentences, Democrats in Congress have mostly stood behind the president, at least publicly. Many conceded the president had a poor performance but asserted that he should be judged for the entirety of his presidency rather than a 90 minute debate. But at the same time, some Democrats have argued that Biden’s top aides and staffers have kept the president in a bubble, protecting him from the harsh realities of the campaign.

“It’s clear that what took place last week isn’t, doesn’t seem to influence his decision. I don’t know what will,” Quigley said when asked if polling that showed Democrats would lose the House or Senate could sway Biden’s decision. “It probably takes up to a week to get decent polling … I do think that’s probably the only thing out there right now that could change his mind or influence that critical decision that, again, only he can make.”

So far, Biden has been determined to stay in the race, and his family has urged him to continue on as well. Biden and his aides worked to quell worries about his age after the debate, including at a rally in North Carolina on Friday where a fiery Biden admitted, “I don’t walk as easy as I used to. I don’t speak as smoothly as I used to. I don’t debate as well as I used to.”

“But I know what I do know: I know how to tell the truth,” he said.

On Tuesday, Sen. Peter Welch (D-Vt.), said that the Biden campaign’s dismissive approach to squashing questions about the president’s age, especially by calling people with those concerns “bed-wetters,” is “inappropriate.”

“I really do criticize the campaign for a dismissive attitude towards people who are raising questions for discussion. That’s just facing the reality that we’re in,” Welch told Semafor. “But that’s the discussion we have to have. It has to be from the top levels of the Biden campaign to precinct captains in the southside of Chicago.”
