My personal belief is that GWB may have been following a variation on Mark Twain's advice, "Substitute damn every time youre inclined to write very; your editor will delete it and the writing will be just as it should be." Bush probably thought the SCOTUS would negate the bad parts of the McCain-Feingold abomination while leaving in the good ones. Even some people here had expressed that sentiment. Foolish to trust the SCOTUS...
No doubt he did. Fortunately there may be one more seat to fill on the High Court.
