I find it ironic that McCain spent ~2 years moving himself toward Bush's positions in order to make himself more electable, only to find out when he got there that (a) it still wasn't enough for the Uber-Republican base, necessitating a choice like Palin to mollify them, and (b) Bush had lost so much popularity that among the rest of the voters, the association was now a liability... leading him to trot out the "maverick" characterization that no longer remotely reflects his position.
