I want to control our own energy by developing oil and natural gas but also the energy sources of the future.

So I'm not proposing anything radical. I just believe that anybody making over $250,000 a year should go back to the income tax rates we were paying under Bill Clinton. Back when our economy created nearly 23 million new jobs, the biggest budget surplus in history, and plenty of millionaires to boot. ... At the same time, most people agree that we should not raise taxes on middle-class families or small businesses -- not when so many folks are just trying to get by.

There are times where I'd say the Oval Office, you use to gather the facts. The decisions you probably make late at night, or at least I do. But there are some times where you think you've made a decision, but during that walk, where you're announcing the decision, you've just got to make sure that, you're prepared to live with it, because as you know George, a lot of these decisions are not - the outcomes are uncertain.
