I’ve met with him, and asked him exactly this question. He told me that he can’t do it on his own, and needs people to go to Washington and demand that Congress listen to them. His election would, in itself, send a loud and clear message to the entire political establishment in America: we’ve had enough of your bullshit, and we’re not going to stand for it any more.
It won’t be easy to get Congress on board, and it won’t be easy to get things done, but it’s going to be that way for any president who isn’t owned by the Koch brothers. So I believe we put a president in the white house who will fight for the people in America who can’t fight for themselves, because they don’t have lobbyists or millions of dollars to buy candidates, and then we help that president by staying involved and forcing change.
It isn’t going to be easy, and it may not even happen during one or two terms of that presidency, but I know that Bernie Sanders is the only candidate running now who can at least start to make the real changes we all hoped Obama would make.
