There has been growing alarm among Democrats about Joe Biden’s debate performance on Thursday, amplifying concerns he can’t beat Donald Trump in November. But so far very few prominent Democrats have publicly called for Biden to step aside. One of Biden’s longtime allies, former House Speaker Nancy Pelosi, said on MSNBC Tuesday that it’s a “legitimate question” to ask if Biden’s pauses during the debate were “an episode or is this a condition?” But she stopped short of calling for Biden to withdraw, saying that people should have concerns about Trump’s mental acuity as well.
