Hot air bubble around Mitt Romney?

I'm near Detroit, about 20 miles west of Dearborn where he announced his bid for the Presidency earlier today. We were supposed to get blasted by a winter storm starting this morning, yet until a little while ago- probably about the time his flight took off- there's been a bubble in the vast field of white on the radar screen, roughly centered on Dearborn, where it wasn't snowing. "Dry air", says the news, but I'm skeptical. Is it coincidence, or empirical evidence that it's the Conservatives themselves that are responsible for the whole global warming thing? And if it's the latter, can we reverse the trend simply by shipping off Romney, Pat Robertson, Marilyn Musgrave, Rick Santorum, Rush Limbaugh, et al to Mars? I say it'd kill two birds with one stone... no more global warming, and in a few years, Mars will be warm enough for a proper colony!
