I happen to be a proponent of a single-payer universal health care plan.

I think it was not a bad idea to wrap Barack Obama in the mantle of Teddy Roosevelt. He`s been assuming a sort of progressive mantle, and he ticked off some large and systemic problems that this country faces.

As has been well documented, I smoked pot as a kid, and I view it as a bad habit and a vice, not very different from the cigarettes that I smoked as a young person up through a big chunk of my adult life. I don't think it is more dangerous than alcohol.

We can't, you know, use our military to make sure the planet doesn't get warmer. And so that kind of leadership, of being able to bring people together, to apply practical commonsense solutions based on facts, based on science, based on what works you know, that's been the approach I have taken consistently as a public servant.
