greg stephens: "Some USA politics looks remarkably sick. Is this sort of smearing and fakery common over there? "

Unfortunately, Greg, smearing, fakery and outright lies are all too common in US politics, and that includes photoshopped photos and videos (not to mention audio and video selectively edited to give an entirely false impression.   I've seen a lot more of it coming from the right than from the left, but it's hardly confined to those of any one particular political persuasion.

"Especially odd that it extends to a folk music forum. Do all political parties have plants operating in all the esoteric forums?"
There are "plants" operating all across the internet, greg. I'm not one of them, though.
I honestly thought this was a real campaign ad that had been aired in Georgia. That's the way it was presented when I heard it talked about on radio.   But if it's been photoshopped, that certainly would make more sense than what it originally appeared to be (an unedited ad that had already aired).

I'm not convinced Chambliss's actions are weird or perverted, any more than I'm convinced that Iranian father was "sexually abusing" his daughter (who also seemed to be quite accepting of his fondling). On the one hand, if the girl in the Chambliss video is completely pre-pubescent and has no "boobs," then he's not really caressing a sexually relevant part of her anatomy.   And even if she's begun to sprout breast buds, her dad or grandfather might be quite oblivious to it (anatomical changes in kids can happen almost overnight, or they can happen so gradually that their parents hardly notice them at first).   
But it's hard for me to believe someone running for re-election -- especially as a conservative Republican in a conservative southern state -- would let a video like that air, when the Zeitgeist today is one of hypervigilance re anything that remotely smacks of "sexual abuse."
