People need to remember that just a few short months ago Democratic voters voted overwhelmingly for Joe to be their nominee. It was obvious then that there were issues but the DNC and the voters still chose Joe. So the sudden panic is a mystery when it has been obvious all along. If they change him out now, the voters do not get a choice. The elite will make the choice. This is what happens in places like Russia and Cuba. This should not happen in the US.
