I think the dynamics may be just the opposite this time. With so many democrat candidates flacking extreme left policies it’s doubtful that one of them will have enough time & money to emerge as a front-runner. This is particularly true with the primary schedule being front-loaded. The only thing that unifies Democrat voters is a hatred for DJT. So they’ll go for the candidate that the Media says has the best chance — and right now that is Joe Biden.
Biden’s problems are manifold. Just last week we saw him flip his position on the Hyde Amendment. He had to do that politically. But that may be his only forced move since he appears to have a bye to the convention. I make his chances 1 in 3 of gettng the nomination. That’s far & away the best odds in this field.
I still say there’s a great big ugly lurker thing lurking behind it all. Right now my money still says Biden is just stalking horse for the pants suit stalky thing - Hellary. He’s there to flush out the current loony bin opposition. (He might be too stupid to know it!) Same strategy as before Hellary will look moderate in comparison.
