However, I can't condone this kind of attack. You're going to attack a candidate because what his son did at a boyscout camp to a dog? Strikes me as rather nasty. This kind of attack is only going to help the Huckster in Iowa; people are going to assume his opponents put it out, which in turn makes them look sleazy.
We ought to be focusing on his record. Between his high spending, high taxing ways, to his giving clemency to any murder who shouted "Jesus," to his corruption, there's plenty of legitimate things upon which to attack him. His son hurting a dog is not one of them.
