>. Elizabeth Warren would make a great running mate for Sanders though.
I think you meant it the other way around.
If Warren had run, she'd get my vote over the others. I do not care for some of her positions, but she has demonstrated an element of accountability in government. In the ideal world I'd prefer a far smaller size of federal government - but if that can't happen, I'd rather pick someone who has a track record of intelligence and efficiency. Warren seems the most devoted in helping middle class Americans.
Sanders is a buffoon. Buffoons are OK as VPs, so long as the president stays healthy.
