What is the environmental platform of the Republican party? I don't know either.

I think that is the fight that we have to wage if we're to save the middle class. And I do have doubts about whether Hillary Clinton or whether any Republican candidate out there is prepared to take on the big money interests who control so much of our economy and as a result of Citizens United, our political process as well.

Free speech is a great idea, but were in a war.

My advice is if we can't replace Obamacare by ourselves, to go to the Democrats and say this. 10% of the sick people in this country drive 90 percent of the cost for all of us. Let's take those 10 percent of really sick people, put them in a federal managed care system so they'll get better outcomes, and save the private sector market if we can't do this by ourselves. That's a good place to start.

What is the environmental policy of the Republican Party? When I ask that question, I get a blank stare, if I'm president of the United States, we're going to address climate change and CO2 emissions in a business-friendly way.

The sooner we get started with alternative energy sources and recognize that fossil fuels makes us less secure as a nation, and more dangerous as a planet, the better off we'll be.

I've got the best job in the world being a senator from the United States, a senator from South Carolina in the United States Senate, representing South Carolina in the United States Senate is a dream job for me, but the world is literally falling apart. And we can't get anything done here at home. So that drives my thinking more than anything else.
