Why is "Romney the Experienced Manager" running such an inept campaign?

By Comrade Misfit

Romney has spent a lot of time touting his experience at managing businesses and making them work. What he doesn't spend as much time bragging about is the fact that he has been running for the presidency for the last seven years.

So why is he now stumbling so badly? Why does he say the stupid things that he has been saying? Why does he tolerate having a senior staffer who is laboring under the delusion that the Soviet Union still exists?

And when he screws up, why the frak doesn't he just say so and then move on? His doubling-down on his gloating over the slaying of four American diplomats in Benghazi was unseemly and may have hurt him badly.

This campaign is by no means over. But if Mittens loses, I'll bet that the pundits will mark mid-September as the beginning of his failure.
