Matt: For whatever it's worth, I've been hearing such tales of vandalism from both Bush supporters and Kerry supporters. Naturally, both assume that the vast majority of these attacks are directed against their side.
There is a lot of hate out there. The country might not be "polarized" in the sense of an ideological war—the gap between Kerry's and Bush's beliefs simply isn't that wide, and there's a substantial number of Americans who don't really care who wins—but the fanaticism of the hardcore Bushbots and Kerrybots really is something to behold. I get their e-mails, and I don't have any trouble imagining them vandalizing someone's car, sign, or lawn. Anything to save America from that Communist sleeper agent Kerry or that Nazi goon Bush.
