That's honestly what I love about Bernie's campaign. He proposes allof these changes, but he doesn't outright say he is going to do them. His platform is a call to action for the American people. TOGETHER we can bring change that betters the entire country. If you watch the Republican debate, you hear a lot of "If I'm elected I will do this..." which is an inherently false statement as the presidency doesn't work in that capacity. Hopefully Sanders is driving force of the populist movement in the US. In regards to Sanders being in senate. Look at the state he comes from Vermont is pretty liberal...

It's actually interesting because Vermont has become much more liberal in the last two decades or so. I think prior to that they were severely republican. I think that would probably be the reason for them being a swing state. I honestly thought they had a larger liberal leaning than that though.
