GOP Rep Richard Pombo — who's locked in a tighter-than-expected contest with Dem Jerry McNerney — has just released a new radio ad claiming that McNerney "thinks the war on terror is a joke." The ad goes an extra step and accuses McNerney of saying "that North Korea should be allowed to develop nuclear weapons without fear of U.S. military intervention." In a final display of stock GOP rhetoric, the ad insinuates that if you vote for the Dem, you just might, well, die. It concludes: "Is there a difference between Richard Pombo and Jerry McNerney on the war on terror? You bet your life there is." Listen to it here.
