You are wrong. Palin never "taxed" oil companies. You should really the learn the facts about what she did.
Actually, she DID. She pushed through a $1.5 billion "windfall tax" on oil companies - and that at a time when Alaska had a budget SURPLUS. She was all about forcing the oil companies in Alaska to "share" their hard-earned profits with the good people of Alaska, even though most of those people had done nothing to help the oil companies earn those profits in the first place. Hardly a record that inspires confidence in her commitment to fiscal conservative principles. Like a said, being a populist isn't always a good thing.
But hey, it's for the kids, youbetcha.
