How about Article I, Section 7. Yes, the President does have a part to play in spending if he chooses to exercise his powers.
Presidents don't write bills, they sign them and they have no line item veto.
Its up or down, and a President can't veto everything.
Congress makes the bills and spends the money. Case Closed.
When you advance the notion "President X run up the budget" you further reinforce the ignorant masses that the President does it all. They don't. They never have and if we can get folks like yourself to use proper rhetoric when talking about politics hopefully they never will.
Don't reinforce the notion that Presidents do something they can't. Its why we get the idiots we do who take up residence at 1600 Pennsylvania Ave. Witha notion like "If I am elected President I promise a chicken in every pot and an Xbox for every living room." People believe stuff like that because we have people saying "Reagan ran up the budget" and no one refutes what is clearly impossible due to the Constitution.
Remember Congress CAN pass legislation without the President. Presidents CAN'T do so without the Congress.
