Line-item veto
People who like the line-item veto say that it is good because it allows the President to remove unimportant waste from important legislation.  For example, it would be too dangerous to completely veto big pieces of legislation (like the budget for the military or the budget for other government departments), but with the line-item veto, the President could choose to keep what he or she thinks are the good parts of the bill and reject the bad parts of the bill.
