That's all you need to say. Here's two truisms: Corporations never actually pay taxes, and career politicians never get hurt.
The scurry to the left is because they know there's loyal broken-glass moderates who'll vote for change every time. Conservatives continue to prove that they can't be counted on. Ask Rick Santorum.
God willing they will rue the day for going left. I can see a time not too far from now where the dems will have a super majority in both houses and have a president in the WH to boot.
career politicians never get hurt.
I'm a big believer in term limits. That problem would be on the way to being solved. They would be out of there before cronyism and one hand washes the other could take root.
