At the foreign policy debate, President Obama thought he was putting something over on Mitt Romney when he acted as if the Republican was an imbecile for suggesting that the rapid decline in U.S. Naval strength was anything but a good idea:
You mentioned the Navy, for example, and that we have fewer ships than we did in 1916. Well, Governor, we also have fewer horses and bayonets, because the nature of our military’s changed. We have these things called aircraft carriers, where planes land on them. We have these ships that go underwater, nuclear submarines.
That was quite a zinger. In one fell swoop, he portrayed the Republican as ignorant about defense issues and established himself as the competent commander-in-chief. Except for the fact that he was dead wrong and did himself far more political damage than good.
