The Tennessee Democratic Party's latest insertion into the mayor's race is a mailer that includes the Gadsden rattlesnake and says David Fox is a Tea Partier. Steven Hale on it:

It's not meant to make an argument or change a single vote. What it's meant to do is stampede the complacent Democratic voter who will open his or her mailbox, startle at the sight of those words and that rattlesnake, and then make haste to a precinct. The party knows the race is close, and it must be convulsing at the thought that a candidate endorsed by anti-municipal schemer Casada could be mayor of the state's capital city -- a Trojan horse for precisely the kind of extremists Fox isn't, but Casada is. So they're trying to scare the faithful to the polls. (Or they just want to encourage Democrats to take up good civic habits like voting, no matter who it's for.)
