From the link:
"On June 26, 1998, the Supreme Court, in a 6-3 decision, struck down the line-item veto law, declaring it unconstitutional. In the case of Clinton v. City of New York, the Court held the law unconstitutional on grounds that it violates the presentment clause; in order to grant the President line item veto a constitutional amendment is needed (according to the majority opinion)."
I didn't know the line item veto was struck down. Must have missed it. Without a line-item veto the bully pulpit is all W has ... and he's not very good at being a bully with the 'Rats, let alone his own party.
