The reality of Trump agressively campaigning and traveling is forcing Biden out of his basement. The sight of him mumbling and bumbling over the next few weeks cannot be hidden and Democrat candidates will more than panic. Suspect there will be a concerted effort among Democrats to get him to withdraw.
Too late to pull the plug on Biden. If they get him out now the Berniebots will really go haywire especially if they put in someone other than him. The RATS are stuck with Biden. My guess is they’ll concentrate all their efforts on winning the Senate and retaining the House. That way they can keep Trump at bay and bide for time again until 2024 when they can put a better presidential candidate on the ballot.
