AMERICAblog points to this interview, containing the following fantastic exchange:

[Some local news anchor]: Well, you say you're sure [Palin] has the experience, but again, 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 probably anyone else in the United States of America. She represents, is a governor of a state that 20% of America's energy supply comes from there. And we all know that energy is a critical and vital national security issue. We've got to stop sending $700 billion of American money to countries that don't like us very much. She's very well versed on that issue. And, uh, she also happens to represent, be governor of a state that's right next to Russia. She understands Russia, and their newly aggressive behavior in the world which is also something we have to be very concerned about.

Hear that, you stupid liberals? She knows more about energy than probably anyone else in the United States of America! So shut up already!

The Washington Monthly's Steve Benen objects:

I'm afraid this is just embarrassingly incoherent. First, the notion that Palin's proximity to Russia counts as national security experience continues to be unusually stupid, even for McCain.

Second, "Energy" is not a response to the question, "What experience does she have in the field of national security?"

And third, to insist, publicly and on the record, that Sarah Palin "knows more about energy than probably anyone else in the United States of America" is, quite literally, laughable. We are, after all, talking about a politician who isn't sure about the human impact on global warming, and hasn't demonstrated any real expertise on the issue. Ever.
