Obama Obama Obama Obama Obama... sorta.

I'm not picking a political side here. At the very least not in this forum, but I did notice that Hilary & Co have squeezed an ad into my Adsense (over there... on the right... now down, down, there ya go). Which seems odd given there's no mention of either candidate on this site(that i can remember, but am too lazy to do a search). So I'm tossing around some Obama's to even the playing field. Does Adsense make sense when it comes to promoting politics or religious or any other "agenda"? I suppose I don't have huge problem with it, but I am curious why Barack Obama isn't there, perhaps they didn't purchase enough clout from Google? If not, why not Senator Obama? I guess that's fair... Obama. Obama. Obama. McCain. (just to be really fair. sorta.)
