Sen. Peter Welch (D-VT) became the first Democrat in the U.S. Senate to call on President Joe Biden to end his re-election campaign following his disastrous debate performance against former President Donald Trump.

In an op-ed published by The Washington Post, Welch acknowledged that like millions of Democrats around the country, he is “worried about November’s election.”

“We cannot unsee President Biden’s disastrous debate performance. We cannot ignore or dismiss the valid questions raised since that night,” he wrote, later adding that Biden needed to “reassess whether he is the best candidate to” take on Trump in the election.

“In my view, he is not,” Welch said. “For the good of the country, I’m calling on President Biden to withdraw from the race.”

He said that the national conversation is solely focused on Biden’s “age and capacity” following the debate.

Following the debate, polls have shown Trump’s lead over Biden become even more dominate as the president falls behind across the country, especially in swing states. The Wall Street Journal found that 80% of voters now believe that Biden is “too old” to be president.

He falsely claimed that states like Arizona and Georgia are “strongholds” for Democrats as he noted that numerous states that went for Biden in 2020 are now turning Republican.

“Vice President Harris is a capable, proven leader, and we have other electable, young, energizing Democratic governors and senators in swing states,” he wrote. “Not only do these leaders have experience running and winning in tough political environments, they also have fundraising networks, media experience, charisma, and the ability to inspire voters across generations and across our big tent.”

“We have asked President Biden to do so much for so many for so long,” he concluded. “It has required unmatched selflessness and courage. We need him to put us first, as he has done before. I urge him to do it now.”
