If Obama does allow Congress to vote on the use of military force, it's unclear if the unholy alliance of the right and the left would stay united to oppose any military attack.
There are "not so many consequences for posturing on the issue," Hurlburt said. But there are a lot more consequences for taking a vote on it.
