Sanders on a third party candidate

In this interview he basically said that even though Clinton and he diverge on several issues, at this point he will support her because the alternative in Trump would be a YUGE disaster for this country. He admits that people don't trust Clinton's change of view on for example the TPP or the Keystone Pipeline. And that her work is to convince us she's authentic about it. So for this election Sanders is not going third party, but we can hope that if Clinton is elected, and she and the Democratic Party continue to feed the corporate beast, he'll change his tune and start turning his campaign machine into a progressive third-party movement.
