It didn't take anytime since Obama got the nomination for the Repubs to start up with the "Mushroom Cloud" business again. You can tell they have their talking points, most pundits call him the "ultra liberal" or "most liberal senator," and the best is Thomas Sowell talking about Iran and the terrorists and how they'll "make 9-11 look like child's play" and neighborhoods will explode from "radioactive mushroom clouds." God help us if people fall for that again. I actually worry more what will happen with food and gas if we're not blown up in the next few years.
