I keep hearing his internal polling and congressional internal polling is not good, which is why the chorus of “drop out Joe” is happening.If reporting of "sources" is to believed, the Biden staffers acknowledge that he cannot win in Arizona or Nevada (or Georgia). His path to victory relies on winning "the blue wall", 3 states he's losing.
He's going to have to make up ground, convince the overwhelming majority of voters - including the majority in his own party - that he isn't too old for the job, while overcoming his record low approval ratings.
That doesn't mean it's impossible, but it's a long shot.
