Ugh I really hope it is zero. Having a the POTUS and VP have an average age of 70 (78 in 8 years) is not a good idea. The VP needs to be a young up and comer within the party and someone they can look for in the future. She could promise him a spot in her cabinet or in some advisory role in which he can help push a couple of his agendas. But he really makes no sense as a VP candidate, considering his pretty radical overall agenda. At the end of the day, a decent amount of the people who voted for Bernie will vote for Hilary, the "bernie bros" may not, but they are mostly made up of young 20 something white voters, that demographic never comes out to vote in general elections anyways. I would hate to see the demographic party be held hostage due to a very vocal minority of people (the true Bernie or Bust people) Even if they can't reach that group, it's still not a huge deal IMO. You are going to have a ton of women, minority and moderate republicans who refuse to vote for Trump this election. They may not vote for Hilary, but they won't come to the polls at all. Hilary's "challenge" of reaching the bernie bros is a much less difficult one than Trumps "challenge" or reaching the moderate republicans/middle of the road folks. I thought for sure he would tone down the racist rhetoric once he won the nominee, but with the embarrassing judge comments recently it looks like he is just doubling down. I have a lot of friends and some extended family who have voted republican the majority of the time, to almost a person I haven't heard a single one say they will vote for Trump (now maybe some will, but won't publicize it) but mostly I hear them split between not voting at all, or voting for Hilary. I don't see any way Trump turns a few blue states red (and keeps all the previous red ones red) from the last election. I could even see him struggling to win a state like Texas when it's all said and done.
