Bush can veto for any reason he sees fit. One really good reason is the constitutionality of the bill, if Bush thinks its unconstitutional, he has the sole authority to uphold his oath of office and veto the bill.
Earlier in the thread you acknowledged these facts and stated with certainty, that the congress would over-ride so a veto was a waste of time.
How are you so certain?
Don't you tink that Bush would save face with conservatives if this trash passed over his veto, instead of his endorsement?
Triple, out.
And even though I still don't see where he and he alone can decide that a bill is unconstitutional, perhaps he WANTS some of the bill, like the $2000 hard money.....and perhaps he believes this is the best way or the only way he'll ever get it.
