What was Gov. Rick Perry "on" in New Hampshhire today?

We’re all used to seeing Gov. Perry speak in staid tones, often looking strong with jaw jutting forward as if he were posing to be the next head added to Mount Rushmore. Today something came unglued. In a speech to a conservative group in New Hampshire, Perry bounces, gestures wildly and grins like the proverbial Cheshire Cat. Some thought he was drunk. I thought it looked more like a cocaine high or maybe a large enough dose of oxycontin to produce elation.

Is this going to be remembered as Gov. Perry’s version of the Howard Dean Yehaw yell? What do you think? Unpresidential or no big deal.
