FWIW, the policy described in the article has now been repealed, and was almost unanimously. And Anoka County normally wouldn't elect people like Bachmann, but the district lacks the appendage that runs down to Minneapolis (which is quite Democratic) and the town of Coon Rapids (a swing area that wouldn't vote for her.) Bachmann's support mostly comes further out places like Tom Emmer's home county of Wright, and Sherburne which famously used to elect a State Rep who compared Democrats blocking the gay marriage amendment to communist persecution of Christians, and was primaried after being arrested and convicted for beating his wife with the Bible (like literally. He'd strike and toss Bibles at her.) Sherburne County is also home to a car dealership know for its sign which frequently changes to random Bible verses, and Wright County is formerly home to this bank which was later shut down by state regulators in 2009.
I'm surprised of the whole fundie influence in that neck of the woods. According to this link, it doesn't seem that there aren't too many of them.
