again that was voted for in '05. When we talk about energy, we have to consider the need to do all that we can to allow this nation to become energy independent. It's a nonsensical position that we are in when we have domestic supplies of energy all over this great land. And East Coast politicians who don't allow energy-producing states like Alaska to produce these, to tap into them, and instead we're relying on foreign countries to produce for us. PALIN : We're circulating about $700 billion a year into foreign countries, some who do not like America -- they certainly don't have our best interests at heart -- instead of those dollars circulating here, creating tens of thousands of jobs and allowing domestic supplies of energy to be tapped into and start flowing into these very, very hungry markets. Energy independence is the key to this nation's future, to our economic future, and to our national security. So when we talk about energy plans, it's not just about who got a tax break and who didn't. And we're not giving oil companies tax breaks, but it's about a heck of a lot more than that. Energy independence is the key to America's future. IFILL : Governor, I'm happy to talk to you in this next section about energy issues. Let's talk about climate change. What is true and what is false about what we have heard, read, discussed, debated about the causes of climate change? PALIN : Yes.
