‘Bams is many things but stupid isn’t amongst them. He had a plan and he’s been implementing it.
I think it is more a 1/3 – 1/3 – 1/3 mix. 1/3 will vote Republican no matter who the candidate is. 1/3 will vote Democrat no matter who the candidate is. The remaining 1/3 are the folks in the middle who can be persuaded to go either way. They’re the ones who decide elections. Many in that middle 1/3 are unhappy with ‘Bams currently but that does not automatically translate into their not voting for Hillary. Come across as too extreme left wing or too extreme right wing and you’re not going to get that middle 1/3. Part of the problem is that the middle 1/3 don’t tend to vote in the primaries and so come the actual election they often vote whichever they think is the lesser of two evils.
