Well, we just dropped the youngest Centerfielder off at her first grade classroom and stopped off at her school cafeteria to vote. Her school is the closest elementary school to the University of Michigan's campus, so the polling places were being manned by UM students. The only candidate's signs I could see anywhere near the school were for Romney.
If you know UM, there's a large rock on the corner of Hill and Washtenaw, about 5 to 6 feet high, called, appropriately, "The Rock." The Rock gets painted often, by frats and sororities during rush week, by students of opposing universities before big games, by birthday celebrant's friends, by local schoolkids to thank their teachers (as the eldest little Centerfielder did a few years ago).
Today the Rock is painted blue, says "Romney '08" on it, and is surrounded by Romney signs. Again, I have seen few other candidate's signs around town. The People's Republic of Ann Arbor is about as blue as you can get in a purple state, so my guess is that the effort to get Democrats to vote for Mitt is behind this.
Anyway, I voted for Mitt, and I believe it's the only time I've ever voted for a Republican. If you're in Michigan and voted for Mitt, take the poll.
