"I voted against the surge before I voted for it."

This is the only reason for the non-binding resolution: so that later on when everyone's running for office again they can say that they voted against the surge before they voted for spending the money on it.

The next thing that will happen, after the Pres ignores the Congress' resolution and goes on with his surge plan, is that he will ask Congress for the money to pay for it. These politians know that if they vote against the money (the infamous "power of the purse") they will be branded as "anti-military" and "not supporting the troops". The power of the purse may be what the Framers intended for Congress to wield, but it is political suicide when applied to military concerns.

So the only way out is to first pass the "We don't like the surge" bill and then pass the spending bill, and when asked on the campaign trail in a couple of years they can say,

"I voted against the surge before I voted for it."
