I know what you mean, but I don't think there will be enough caving GOP congressmen to override any vetoes. If Bush does veto something - or at least threaten and mean it - the congress won't be able to do anything too crazy.
Some senators maybe, but Reps have to run again in two years, their reelection campaigns start again very soon, in fact about 5 hrs from now tomorrow morning. Many of them will look at the piles of Republican corpses and put their fingers in the wind and start checking the signs.
Sorry I just do not see a "stand and deliver" attitude coming out of this. And the mainstream media will do everything to quash any such notion.
