Why is this Bush's fault?

The RCP Blog assesses why some of Bush's proposals foundered in Congress. It seems to me that this is more the fault of Republicans in Congress than Bush's. Frist will not go down as one of the effective majority leaders in history. Ultimately, it's a problem for Republican voters. We elected five vote majority and found that it included too many RINOs, and ADD sufferers, like those in the "gang of 14" who dither and put their relations with the Democrats ahead of the need to govern.
