I have a feeling this story is going to get a lot of coverage again if and when Mitt Romney locks up the GOP nomination. Watch the video as Rachel Maddow revisits the story of Mitt Romney and the unfortunate incident when he placed his dog on the roof of his station wagon for a 12-hour road trip. At one point the dog became so scared or irritated that he defecated on the roof of the car. The story is pretty gross.

There are web sites sprouting up around the web (see Spreading Romney) and Newt Gingrich is also bringing this up in a web ad.

Small things like this can have a big impact on a campaign. With the Internet, you can see dog lovers making this a big issue. It doesn’t help that Romney already comes across as a stiff robot.
