Google puts up the ads as their adsense algorithm dictates. I think all the "Romney sucks" thread titles gave adsense the idea to put up Romney ads. Or Romney simply bought so many they came up pretty much everywhere...
The ads you see are unique to your own internet activities. Looks like you have a fetish. Thanks for letting us know!
Cheer up, mobes, it could be worse.. I used to get Romney, now I get ads for plus size clothing. And I'm not plus sized!
