I think President Obama could have handled politics and policies differently. But he has been decisive, strong, and consistent - important qualities in a president. Mitt Romney is indeed an Etch A Sketch, the antithesis of leadership.

I don't like politicians who vacillate.

I would very honestly just tell you that what I tried to do was simply respond to inquiries from people as they came in. Where I've thought I could say something useful, I've tried to add a voice that was, frankly, a dissident voice earlier on, but one that I think has become a more mainstream voice-and not because I've shifted. I think that the critique I had of what was going on in our financial system from six, eight years ago-after seeing some of what we've suffered through and even since the cataclysm itself-in terms of the structural changes.

In politics you learn to always smile.

We are all used to paying a sales tax when we buy things - almost 9 percent here in New York City. The application of this concept to the financial sector could solve our need for revenue, bring some sanity back into the financial sector, and give us a way to raise the revenue we need to run the government in a fiscally responsible way.

I don't have any particular expertise-I've never been a banker or an investment banker. But I did see an evolution in the system that I thought was problematic.

I have long said there are three distinct groups under the GOP's tent: theological warriors, who want to impose their social views on the rest of society; Tea Party zealots, who say with a straight face that they want the government to get out of their Medicare; and remnants of the pro-business moderates.
