John McCain, a key figure in efforts to pass comprehensive immigration reform, responded to criticism from fellow presidential candidate Mitt Romney by telling bloggers on a conference call,
Maybe I should wait a couple of weeks and see if [Romney’s position] 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.
Politico has the audio. The “varmint” line refers to Romney’s efforts to square his claims of hunting experience with lack of hunting license, while “those Guatemalans” are presumably those employed by Romney’s landscaper.
