Other than that he hates Trump, but why???
I honestly cannot think of a single Sanders policy I like.
But as others have said, he sticks to his principles no matter what the cost. In that way, he reminds me of Ron Paul. Neither one of them ever got anything accomplished, but they remained pure to the end.
We need purists on each end of the spectrum to keep us from being pulled entirely in one direction or the other.
The Ron Pauls and the Bernie Sanders make us think about ideas we otherwise would not have. But most importantly, they make us see problems we otherwise would have missed.
