At a rally in Madison, Wisconsin last Friday, Joe Biden said: “Some folks … are trying to push me out of the race.” To whom was the president referring?
Certainly not to Donald Trump or the Republicans, who have been uncharacteristically silent about the whole question of whether Biden should drop out. They couldn’t push him out of the Democratic race anyway.
