We need to reduce our dependence on foreign oil by ending the subsidies for oil companies, and doubling down on clean energy that generates jobs and strengthens our security.

Congress has become so dysfunctional that more and more of a burden is placed on the agencies to fill in the gaps. And the gaps get bigger and bigger because they're not constantly refreshed and tweaked.

I am willing to work with anybody who wants to have a serious conversation about our fiscal future. We're not going to do this under the threat of blowing up the entire economy. I will not negotiate over Congress' responsibility to pay the bills that have already been racked up. I don't know how I can be more clear about this.

It's not a nice-to-have - it's a must-have. It's time we stop treating child care as a side issue, or a women's issue, and treat it like the national economic priority that it is for all of us.

Increasing America’s debt weakens us domestically and internationally. Leadership means that 'the buck stops here.' Instead, Washington is shifting the burden of bad choices today onto the backs of our children and grandchildren. America has a debt problem and a failure of leadership.

For the sake of our children and our future, we must do more to combat climate change. Now, it's true that no single event makes a trend. But the fact is the 12 hottest years on record have all come in the last 15. Heat waves, droughts, wildfires, floods-all are now more frequent and more intense. We can choose to believe that Superstorm Sandy, and the most severe drought in decades, and the worst wildfires some states have ever seen were all just a freak coincidence. Or we can choose to believe in the overwhelming judgment of science-and act before it's too late.

This is something that I'm sure I'd have serious debates with my fellow Christians about. I think that the difficult thing about any religion, including Christianity, is that at some level there is a call to evangelize and prostelytize. There's the belief, certainly in some quarters, that people haven't embraced Jesus Christ as their personal savior that they're going to hell.
