Joe Sudbay is rightthis interview, in which McCain is challenged to explain why Governor Palin is qualified to be a 72-year old heartbeat away from the presidency, is terrible.

But I’m most interested–disturbed, really–by his latest explanation of how Sarah Palin is qualified on the matter that McCain says matters most: national security. 

Reporter: You say you’re sure she has the experience, but I’m just asking for an example. What experience does she have in the field of national security?

McCain: Energy. She knows more about energy than uh probably anyone else in the United States of America. She represe–is a governor of the state that 20% of America’s energy supply comes from there. And you all know that energy is a critical and vital national security issue.

McCain is basically arguing that serving as governor of a state that supplies a lot of America’s energy gives a person great national security credentials.

Hmmm. Governors of states that supply lots of energy … states that supply lots of energy … lets see, those would include Alaska, Louisiana, …

Ut oh.

And Texas.

Now aside from the fact that McCain is wrong about his claim that Alaska provides 20% of our energy supply (it provides 20% of our oil, relatively little–at least thus far–of our natural gas, and insignificant amounts of coal, nuclear, wind, or solar power), he’s basically arguing that a guy like George Bush has the national security qualifications to be President.

And we saw how well that worked out. 

All in all, I’d say, McCain’s making a great case for voting against Sarah Palin.
