The local branch of the Christian Coalition is suing Diane Linn, Maria Rojo de Steffey, Serena Cruz and Lisa Nato. The CC's red herring is that these Commisioners "misspent" County money by allowing gays to marry. "The suit ask the defendants to return to the county general fund money spent by the county in issuing marriage licenses to same-sex couples". The suit is being on behalf of someone named Johny Alan Belgarde. According to the article he is the Grand Wizard of the Christian Coalition of Oregon (OK, it actually says "director").
This is a common tactic, if the law doesn't go your way attack the individuals involved directly. The implication being they will use any means to persecute anyone who opposes them, until they get their way.
I would post an URL to this article, but the Oregonian doesn't seem to have it online. :(
