That's actually why I put up the link and the thread. I cannot imagine he'd be vp for 8 years and not run. But, getting him out might have been one of Gates' motivations for that book.
Biden is such a boob and an endless gaffe machine I can't imagine that even liberals want him to run. While in the long run, the liberal tide is winning, in the short run the Democrats are highly vulnerable in the next couple elections just like W was at the end. What scares me is the Republicans long proven, deep ability to pick candidates who suck.
That meme comforts you. But it has no relationship to the truth.
