People don’t elect cardboard cutout candidates and frankly a cardboard cutout has more appeal than Biden. Cardboard doesn’t molest people, generally speaking.
Well, you are right again. For that reason, some of us believe Biden may be replaced at the last possible moment and might not even be on the ballot.
But if he is the successful candidate, it will be understood he is to be quickly replaced. They just need to hang onto Hillary's popular vote and "fix" the electoral college votes.
