My friend Jason, who reads AmericaBlog just to be "thankful I am not John Aravosis," just sent me an email about how Aravosis is feverishly deconstructing video that's meant to be possible evidence that McCain had a stroke onstage. Regular video, slo-mo video, screen caps—it's quite the investigation over there.
Anyway, J says: "So Aravosis speculates that McCain had a stroke. Well, I know from my experience as a condescending ass: When you are accustomed to contorting your face with various expressions of disdain and contempt, your muscles atrophy a little and sometimes the odd flinch occurs to compensate."
And thus ends the Shakesville investigation into the Great McCain Twitch of 2008.
