If Bush cannot use his best judgement as to the constitutionality of the bill and act accordingly, then why did we even bother to administer to him his oath of office?

At the risk of repeating myself time after time, where EXACTLY in the Constitution does it say that the POTUS can decide a bill is unconstitional ON HIS OWN and just not sign it?

And remember, if you give this "right" to THIS POTUS, you're giving it to all the ones that follow him, you know, the ones that will be elected when you stay home.

POTUS can veto a bill for any reason he likes. He does not have to explain his reasons, he may do so if he chooses. If Congress disagrees they are free to override. Always been that way.

So, POTUS is just a rubber stamp mechanism for ... what higher governing entity are we missing here ?

"Where in the constitution does the president have express authority to veto?" paraphrase of howlin in #49 (duh)

Right here:Section 7. All bills for raising revenue shall originate in the House of Representatives; but the Senate may propose or concur with amendments as on other Bills.

Every bill which shall have passed the House of Representatives and the Senate, shall, before it become a law, be presented to the President of the United States; if he approve he shall sign it, but if not he shall return it, with his objections to that House in which it shall have originated, who shall enter the objections at large on their journal, and proceed to reconsider it. If after such reconsideration two thirds of that House shall agree to pass the bill, it shall be sent, together with the objections, to the other House, by which it shall likewise be reconsidered, and if approved by two thirds of that House, it shall become a law. But in all such cases the votes of both Houses shall be determined by yeas and nays, and the names of the persons voting for and against the bill shall be entered on the journal of each House respectively. If any bill shall not be returned by the President within ten days (Sundays excepted) after it shall have been presented to him, the same shall be a law, in like manner as if he had signed it, unless the Congress by their adjournment prevent its return, in which case it shall not be a law.
