Strawman. When 300+ members call for a democrat takeover in 2006 the nicest terminology is "troll" the correct phrase would be traitors. Bush is not even a consideration in electoral politics. He is not going to run again so it makes no difference how the unappeasables feel about him.
Is your definition of calling for democrat takeover one who says they are not excited enough to go vote in November because the republican party abandoned them?
