Yeah, this is nasty -- though it's not the first time wingers have delighted in their own scintillating wit after making an Obama/outhouse joke:
Outside the Montana state Republican Party convention this weekend was an outhouse labeled the "Obama Presidential Library" and covered in painted-on bullet holes.There have been politician poop jokes since at least the days of Nixon and Agnew (oldsters will remember this poster imagine Nixon on the crapper), so, um, neither side has taken the high road on this sort of thing.
Inside the outhouse contained a fake birth certificate for Barack Hussein Obama, according to the Helena Independent Record....
But I do find a particular category of anti-Obama poop/outhouse merchandise that I don't find for any other politician:

Don't like that design? You can get a stein with this variant:

Or one of these, or one of these, or one of these...
I just don't find this for any other pol: "Back in a minute -- I have to a Bush"? No. "I have to take a W"? No. "I have to take a Romney"? No. "I have to take a Palin"? No. "I have to take a Clinton"? No. This seems to be limited to Obama. Draw your own conclusions as to why other pols are linked to crap, but right-wingers laugh when you say Obama is crap.
