Quote:I disagree.

 

I think that 20% is probably a little low, but much closer to accurate than the 80% you suggest.  The large majority of those who were most vocal in their support of Bernie Sanders are millennials.  They bought into his message because he was anti-establishment, anti-Wall Street, anti-capitalism, anti-corporate America....  While their candidate was certainly malleable enough to abandon all of these stances by endorsing Clinton, I would doubt the young ideologues are going to be anywhere near as willing to abandon their core beliefs.  

 

A good portion of his former supporters simply won't vote.  They're not motivated enough if they don't have a candidate pandering to them. 

 

Another large bloc of his supporters will register protest votes against Hillary by voting for candidates like the Green Party, Libertarians, Socialist candidates, and yes, even Trump. 

 

I honestly think the best case scenario for Clinton in capturing the Sanders vote is around 25-30%.  They're not going to be nearly as willing to sell out as their candidate was.
