The saddest thing (from an outsider's pov) is that it seems Bernie could've won.
Must check out a copy of this book.
Probably not?
He lost the primaries, by a lot. It was never in much doubt once states started voting and it became clear.
He especially lost in battleground states, suffering several 30+% curb stomps in states that are vital during the general election.
He lost, despite having almost no resources on either side spent to attacking him.
He lost, under rules that were basically a copy-paste of the 2008 rules, but with less BS. If Michigan or Florida 2008 happened, Sanders supporters probably would have murdered somebody.
Before voting started, Hillary was routinely beating him in head-to-heads with Trump, and Sanders only gained after he essentially lost the primary, because he managed to fleece $100 Million more dollars from his supporters that was used to inflate himself and make his supporters loathe Hillary and the Democrats, while closing the actual primary gap by, like, 1-fucking-percent.
The only circumstance where I'd say "Sanders would have won!" is if sexism was a gargantuan part of Hillary's loss, rather than just a big part of her loss, and that there's a bunch of reasons why sexism matters way more in a general election rather than during a primary.
Other than that, he got completely fucking stomped during the primaries, for a bunch of obvious, logical, demonstrable reasons.
