If'n I were President, I'd veto any bill that was attached to something else. If it can't stand on it's own, it shouldn't be a bill.
Course, I'd also cut the size of the Fed gov't by 60%.
I'd like to see a constitutional amendment that any expenditure of public funds must be approved line by line. No earmarks, riders, amended bills, or any other BS period. If you are going to spend the people's money on it, let the people know who wants it, how much, and why so they can vote your ass out next go round.
