My wife has been my closest friend, my closest advisor. And ... she's not somebody who looks to the limelight, or even is wild about me being in politics. And that's a good reality check on me.

I promised to bring change to Washington. The underlying reason for the economic mess we're in has been building for years. It's a fundamental imbalance in which the top 1 percent now gets almost a quarter of all national income.

Any so-called leader who does not take this issue (climate change) seriously or treats it like a joke is not fit to lead
