You're right .. it was stunning. The repubs didn't seem to be that upset about the Kerry shirt - but when he got to the other side .. they were brutal. Too bad there was no connection. Of course, it might come on later .. we can always hope .. once he starts telling his friends about his adventures - the light might suddenly come on.
Here in Massachusetts you see a lot of Kerry bumperstickers (and a fair number of Nader/LaDuke stickers), but not a lot of Bush ones.
Sometime after the election, though, I realized there are a lot of stealth Bush stickers on the roads here: all the yellow-ribbon "I support our troops" stickers.
