Let's be real for a minute here. There was only one correct choice for Hillary's VP: when your primary opponent is getting record enthusiasm, raising huge sums of money through small donations, and drawing even bigger crowds than Trump, it should be clear that his message is resonating and that you need him on the ticket in order to fire up the activist base and get them out in force. It was dumb of her not to pick Bernie, and not shoring up her Left Flank was what cost her the election. Add to that it would have united the party and greatly limited the Wikileaks/DNC hack damage.
But Sanders' popularity is WAAAAYYY overstated. People always bring up how he won the Michigan primary but forget that he was blown out in Pennsylvania, Ohio, and barely squeaked by in Indiana. Also Trump won Michigan by 15+ points even going up against a popular Midwestern governor (Kasich) AND the Michigan GOP primary got more votes than the Democratic primary.
-Ohio was a special case due to Sanders supporters going for Kasich. PA was, indeed, a natural place for HRC to beat Sanders due to Hillary men in Western PA and the Philly suburbs. The fact Sanders even won Indiana was a surprise to most (even though it is a northern state).
I doubt Bernie would have won Ohio, but he would have won MI and likely PA.
