Biden has his handlers who want to retain power. They are the ones who must be “convinced.”
Trump was pressured by the GOPe to withdraw after the NBC tape. Fortunately, he resisted.
The Dems may already be well underway in their effort to steal the election again. Removing Biden could complicate that effort. The Dems are split. Every day that goes by makes it more difficult to drop Biden given the rules that govern elections in various states. And if you are going to steal the election, you could care less about the puppet at the top of the ticket. The people who really run this country prefer a feeble, mentally deficient candidate.
BINGO!!!
