More Republican Math

So Bush magnanimously declared that the troops only have to stay in Iraq for 12 months instead of the 15 that they're currently sweating under. At the same time, Petraeus says that they can't bring anymore troops home from the "surge" because the Iraqi army is still not ready. Let me get this straight. We can shorten the tours but we can't decrease the amount of troops over there? How will this work? We can't get troops from anywhere else because the army is already stretched to the limit.

Oh, wait. This is The Math. You know The Math Karl Rove cited when he guaranteed a Republican win in 2006.
