If you want to cut the deficit, the answer is obvious: modify the budget. It makes no sense to pass a budget saying you will spend X, which directly implies borrowing Y, and then a few months later decide you will not authorize that very borrowing you just authorized, and without any plan to deal with the difference.

Where does it end? The answer to that is easy: it ends when a budget is passed where revenue and spending are more balanced. Trying to take shortcuts by playing games with the debt ceiling is a cheap trick that could be potentially disastrous.
