Comment Does it matter? (Score 3, Insightful) 17
Regardless of whatever budget Congress sets, the majority party has already been clear that they have no intent to enforce it. If the president uses the NASA money for something else, or even just puts it into his own personal pocket, we can be confident that he won't be impeached, and if impeached, he won't be convicted.
The only thing that matters is the total budget. The president is free to spend that total however he wishes. This isn't the law as written, but it's the law defacto. If voters have a problem with that (do they?) they can choose a different party to be the majority.
