The GOP did not. Some members of the GOP sided with Democrats to do so. But you'll notice that (most times), the vast majority of the GOP votes against the spending programs. How can the GOP and the Democrats be the same and most votes end up being about 55-45?
A GOP prez has to sign 'em.
No pass, no sign, no spend.
Of course, Bush could have just vetoed the spending programs, but, considering that he proposed many of them, he's not about to do that, is he?
But, in a way, you've made a far more damning case against Bush in regards to fiscal conservatism. Every conservative has his or her breaking point regarding this nonsense. I've just about reached mine.
