Haven't found out so much about his policy ideas but he has an interesting background and skillset.
He's worth a look, and I'd support him against Trump. But that's not saying much as I'd support a horse over Trump.
My current position is that I'd still prefer him to reappear in 8-16 years as a former governor.
Right now, smart and interesting as he appears to be, like Obama I suspect he'd take the first two years of his presidency removing the green from behind his ears.
At the minute, the policy debate is being run by Harris and Warren. I expect Sanders won't get many votes as candidates fall by the wayside.
