Since his dismal debate appearance two weeks ago, some Democrats have openly questioned whether he should still represent the party with others directly urging him to drop out of the race altogether.

Sen. Michael Bennett, D-Colo., gave a blistering assessment of Biden’s reelection bid in a Tuesday night CNN interview, warning that Trump could defeat the incumbent Democrat “by a landslide and take with it the Senate and the House.” And by Wednesday morning, former House Speaker Nancy Pelosi, D-Calif., seemed to question whether Biden should remain the Democratic nominee during an appearance on MSNBC’s “Morning Joe.”

The shift comes after most Democrats in Congress, which reconvened this week, have so far held off on publicly calling for Biden to withdraw following his disastrous debate performance last month − even as many express grave concerns about the odds of Biden beating Trump.
