John McCain: Friend of the Guatemalens

It's already old news in web-years, but John McCain's double judo-chop of Mitt Romney (who's bellyaching about the McCain-Kennedy immigration compromise) represents a mastery of soundbite-fu.

In the case of Governor Romney, you know, maybe I should wait a couple of weeks and see if it changes, because it's changed in less than a year from his position before. And maybe his solution will be to get out his small-varmint gun and drive those Guatemalans off his lawn. I don't know.

"Varming-hunting gun" is a reference to this bit of Romney magnificence. Question: What is it about ornery, aging men and peoples' lawns?
