Revenge of Seamus. Funny political cartoon of Mitt Romney's dog Seamus driving a car with Mitt Romney tied to the roof. The cartoon captions are Mitt saying he has to poop and Seamus telling Mitt he can poop when they get to Canada. Mitt Romney has gained notoriety for his cruelty to dogs during a car trip to Canada. Funny anti Romney shirts, tee shirts and gifts for voters against Mitt Romney in election 2012.
