Well, that is exactly the power, that the line item veto act gives the President. So, you disapprove of the line item veto act. Good!!!
It is the President who looks at any bill as a single bill. A single onion has many layers, but it is still a single onion. He can veto the entire bill, and send it back to Congress with his suggestions and comments about its layers. He can sign it into law, with all of its layers. But he CAN'T sign a single bill into law, and then remove some of its layers. That is unconstitutional.
It has nothing to do with the composition of a bill. It has everything to do with the President's constitutional, and statutory powers to sign bills into law. A President cannot veto, amend, delete any portion of a bill that he has already signed into law. Also, if each bill IS a single appropriation, then how can the President veto only a portion of that bill, after signing it into law? How? What is to stop him from extending this power onto ALL bills? The Constitution? Hence why, a new constitutional amendment would be needed.
Either you think that Congress should give this power to the president(which they can't), or should not. I have given you my reasons. That it is unconstitutional, and that it would undoubtedly be abused by both parties.
The confederate constitution was all about protecting the rights of 11 confederate states. Which included keeping slavery as an institution. The US Constitution is about protecting the rights of ALL States, and all institutions. The Confederate Constitution was a short-sighted, and a divisive document. Many governors already have line item veto powers. So what? The President is NOT the state government. I disagree with you. This is NOT the executive's money, or the Congress's money. It is the people's money, and they should have as much say in how it is spent, as congress or the president.
