Some shadowy nonprofit is running ads accusing John McCain of having cancer. Which is true and actually maybe relevant (the fact that John McCain will be America's oldest president ever is certainly more relevant than Obama's house party with Mr. Ayers). The groups behind the ads are apparently run by nutty lefty filmmaker Robert Greenwald and Howard Dean's brother , and the ads feature doctors (with stethoscopes and stuff) saying that cancer is really bad and might kill John McCain. As an underhanded dirty smear, it at least has the advantage of being, you know, 100% demonstrably true! But still. The ads fail, miserably, by not pointing out explicitly that should McCain die in office, he'd be replaced by Sarah Palin. That is the scary thing here! No one would care if old man McCain died and was replaced by someone with half a fucking brain. Anyway, controversy!!
