President Obama, through health care reform, strengthened Medicare. How did he do that? Well, he found savings by cutting subsidies to insurance companies, ensuring we were rooting out waste and fraud, and he used those savings to put it back into Medicare.

Let me tell you the story about Massachusetts under Governor Romney. It did fall to 47th out of 50 in jobs creation. Wages went down when they were going up in the rest of the country. He left his successor with debt and a deficit, and manufacturing jobs left that state at twice the rate as the rest of the country.

Politics gets me out of bed in the morning It's what really interests me. I'm a competitor, but I also feel like I'm contributing, whether it's working on health-care policy in the White House or out here in Chicago.

Just a few months ago in the Republican primary Mitt Romney said to his opponents, who he was crushing at the time, stop whining. And I think that's a good message for the Romney campaign. Instead of whining about what the Obama campaign is saying, why don't you just put the facts out there and let people decide rather than trying to hide them.

If Mitt Romney and Paul Ryan get elected to the White House, Medicare will be bankrupt by the end of their first term.

I've been very fortunate to work for great people - so even when the political process gets ugly, I find inspiration in the people around me.

There's nothing harder than going on TV and saying something that you don't believe. I don't do that anymore.
