The parts are done for it, if the STS is workable, there still might be a mission.
It's not going to be retired until '06 or '07 as it is, besides if the STS isn't safe to perform the mission, it shouldn't be performed.
Don't blame Bush for it, blame the foam that killed the Columbia for it.
Oh...but you can damn Mondale for it...he's the assclown who spent his time as a Senator going after NASA.
