Remember the story of Seamus the dog? How could you forget? Here's the latest salvo: a member of the group Dogs Against Romney strapped a kennel to the roof of his car with a stuffed canine and a camera inside, then went out on the highway to provide a sort of SeamusCam -- the view of what the Romney family dog would have seen on his infamous journey to Canada atop a Chevy station wagon. It's about as uncomfortable-looking as you'd expect.

But how has it become so memorable? In comparison to other micro-controversies that were supposedly revealing of candidates' character flaws -- from Al Gore's supposed invention of the Internet to George W. Bush's many malapropisms to John Kerry's windsurfing --Seamus' tale has had an unusually long life, even in dog years.
