Yesterday Rudy Giuliani and Mitt Romney clashed over the constitutionality of the Presidential line item veto. I understand that SCOTUS has already ruled it unconstitutional in Clinton v City of New York . But as I understand it according to Scalia's dissent it should've been found constitutional because of The Nondelegation doctrine which evidently is an implied power of the Legislative Branch .
I think Rudi is wrong in his opinion and if he were ever elected would find the use of a line item veto attractive . He certainly exercised the options plenty of times when he was NYC mayor.
My question is ;Can legislation be passed that would give the President a line item veto without having to go the amendment route ?
