I could provide my own analysis, here, but this sums it up pretty well:  
Why Bernie Sanders’s trouncing of Donald Trump may not mean that much
Quote
part of the reason that Clinton does worse against Trump is because of Sanders supporters. The Upshot's Nate Cohn made this point last week, noting that recent YouGov polling showed Clinton leading Trump by 40 points among Sanders voters — and Sanders leading Trump by 70. Trump has benefited from consolidation of Republican support; it's fair to assume that Clinton will similarly benefit once Democrats unify behind her candidacy.

A well reasoned argument is like a diamond: impervious to corruption and crystal clear - and infinitely rarer.

Here, as elsewhere, people are outraged at what feels like a rigged game -- an economy that won't respond, a democracy that won't listen, and a financial sector that holds all the cards. - Robert Reich
