Talk about internet savvy... The Dean campaign has started advertising on deadlymantis. That's right. Look at the top of the page, about a third of the time one of the ads will say:

What does Dean say?
Civil Rights & Justice, American
community, equal rights for all.

Judging by the fact that the other ads are "Lesbian legal services" and something about voting democratic to stop the marriage ammendment, I assume this is a google add tied to some word related to the recent massachussets case.

A bit of sleuthing shows that it comes up on the google search for "gay marriage."
