Well, given the so called unity between them, I think it's fair to assume it ain't happening: http://www.theamericanmirror.com/the-day-after-bernie-never-mentions-hillary-23-minute-speech/
LOL @ Bernie as an establishment lapdog It would be funny as hell, and anger his supporters to no end, but Hillary would never have anyone who is more popular than her. .
Pssst. Hillary probably detests him. Its a bad match of personalities and he is ill suited for a vp roll. She may pick a progressive that meets his approval. I can guarantee, he has been consulted.
Hillary has accepted or integrated some of Sander's policies into her's that was why Sander was ready and did endorsed her after getting some of the things he wanted. Sander is the perfect match against Trump and Pence both of them their policies and history is what Sander and his supporters are fighting against. Sander is a better person than Warren in jamming Trump's insults and bully politics. Sander can soften the impact and pressure that Hillary is facing with her email scandal. Sander can bring experience, voters support, progressiveness, freshness, firmness, fortitude, integrity, and confidence.
I spit up my coffee when I read this. Sanders has less real experience (i.e. accomplishment) than just about anyone serving in the Senate. And having your primary voting block composed of college students looking for someone to bail them out is hardly broad based voter support. Sanders would be a constant pain-in-the-arse to Hillary as a Vice President. Exaggerated "unity" aside, Hillary will never embrace many of Sanders' extreme progressive views, and she won't want to be constantly nagged about it. You can file this one in your closest circular file.
The college students are the ones that will bring out new and all voters. Bernie understand that not all his agenda will and can be accepted same thing too with Hillary both agree they on a common ground a little bit of progressiveness, democratic socialism and capitalism. Hillary and Bernie both compensate each other's weaknesses and strength.
