After that debate, I don't think Biden would have had near the chance of winning. It shocked people that had faith in him and many Democrats wanted him to step down, myself included. If he had stayed in the race, it would have focused on that debate and how unfit he was for office. You had people who were not satisfied with either candidates because of their age.
You saw how energized the Dems were when he stepped down and she took his place. She may not be running if a traditional primary was run, but the circumstances were what they were.
We don't know that Dem leadership knew he was failing.. I'm sure some saw bad days, but we all saw good days too. If he was like he was in the debate on a regular basis, I think they would have intervened sooner... why wouldn't they? The goal is to win the election.
His State of the Union Address was very strong and I don't buy that they had him drugged or any of the other stupid reasons people gave.
It's going to be a roll coaster ride on the 5th I believe, I just hope we have some solid results within a day or two at most. I have early morning meetings on the 6th, but I'll be watching into the weee hours and just try to be alert.
