To be fair, even though I disagree with most of his politics, I did think he had genuine belief in what he said would, from his perspective, benefit the country (he's wrong) and became an outsider for it, which atleast deserves respect in terms of integrity. That said, the fact that he fell in line with the party he's not even technically part of after they wholesale steamrolled him and, more importantly, his voters - not once but twice - shows he puts as much stock in partisan victory as any one else in Congress

I cut Bernie some slack for falling in line even after getting iced out twice. If you are to the left of the Democratic Nominee, and truly believe the GOP nominee (Trump in both cases) is worse for the country, it is perfectly rational to not split the left vote and allow the right candidate to cruise to victory. 

I’d imagine if you could go back and tell Teddy Roosevelt in 1912 his campaign would just guarantee W*lson would win, he wouldn’t have run and split the vote with Taft.

First past the post is a bitch and lesser of two evils strategic voting is a real thing.
