Just to dispel any ideas that I have a political stake in the game myself --- politically I am more on the side of the stay-the-coursers-but-with-50k-more-troops, myself, though I don't have a lot of optimism about how the game will end --- I guess I'm just a natural pessimist.

As an example, and whether we agree or not, one side is calling for "immediate" withdrawal, and the other proposes staying until we restore order.
My main contention is that "staying" does not necessarily equate to "restoring order." As an example, we have stayed in Iraq with varying troop levels, including with force levels beyond what the President has proposed with his "surge". The only constant is that violence has trended upwards, both in terms of attacks on coalition forces and attacks on Iraqi civilians. Empirically the relationship between troop presence and levels of disorder is not related as the poll assumes.
