I like Sanders, while I don't agree with him, I like that he is pretty honest about his feelings even though they don't make for happy, feel good sound clips. Example -

That being said, he isn't going to get it. He's not tied into the right democrats. He's too much of a loose cannon. He's coming off a loss, and "Elect Sanders" energy just isn't there in the country anymore. Speaking of energy, Sanders doesn't have a presidential vibe to him. I think he's good man, but he comes off as old and an odd mix of authoritarian and bookish, school teacherish. It's odd to describe, and it wouldn't be a bad thing in a perfect World, but to be President, you either need swagger or a sternness (ideally a mix of both) about you that Sanders doesn't have.
Trump has it. Biden has the swagger part down, and has been a politician for decades. Also he's tight with Obama, etc.... so he got an automatic in with the black community.
It's interesting, but Jesse Ventura has a really good platform, but he's been out there and "out there" for too long. He also doesn't have Presidential hair.
