Most of the discussion about Biden’s candidacy has revolved around polls and the issue of electability. Biden continues to insist that the shift in public opinion has been small, and that he can recover. Many other Democrats disagree.
But that is the wrong question to be asking at this point. There is no guarantee that any of the other possible nominees would fare better than Biden, even though that seems very likely to me, given that all of them are better positioned to make the argument about Trump’s unfitness than he is. The real issue is whether it is responsible for the Democratic Party to nominate a man who, based on the most recent evidence, is barely physically and mentally able to govern today to run the country for the next four years.
Most of the voters say the answer to that question is no, and with good reason. America is entitled to better than something akin to the last years of FDR or Woodrow Wilson.
