Right wing tax cut zealot/activist Grover Norquist agrees that McCain's tax policies are farther right than even Bush's. "The McCain tax policy is to continue the Bush tax cuts and add three more, so I prefer McCain," he told Salon. "McCain's is bigger, better."
When Grover Norquist is excited about a tax policy, it means that people who aren't rich would be screwed. It's practically a law of physics.
