The creativity of some of McCain-Palin's supporters continues to dazzle and amaze. Here's the latest -- at a rally yesterday morning, a McCain-Palin supporter shouted out: "Obama Bin Laden."You can hear it at the 12-second mark, just before Palin launches into her now-familiar (and false) claim that McCain is too modest to discuss his POW service:It's impossible to know whether Palin heard it. The above vid makes it seem like the person who shouted it was far away from her, but the video posted by this DailyKos diarist suggests otherwise. Earlier today we heard a McCain-Palin supporter shout "kill him" at a Palin rally. TPM Reader MLC asks a very good question about all this: "Where is the Secret Service in all of this? What obligation does the Palin detail have if they actually hear something at one of her rallies?"
