To draw attention away from the other candidate's crazy ideas.
“Why did Slow Joe run in the first place?”
I like a theory by a poster yesterday:
By running against Trump, that allowed democrats to claim that Trump’s investigation of the Bidens’ activities was done to damage his chances.
Did I get that correct, poster?
One theory is that Biden had to run in order to make the impeachment story work. Now, I don’t know if the timeline works, but I suppose it’s possible. After all, Obama did say, “You don’t have to to this, Joe.”
