Tennessee Republicans expect to add to their already considerable advantage in the state House tomorrow. That’s despite the loss of seven Republican incumbents in August primary races. Governor Bill Haslam is predicting GOP supermajorities in both chambers. That would allow Republicans to overcome any procedural challenges by Democrats, and prevent the minority from being able to halt legislative proceedings by walking out. The state GOP spent $1.3 million last month alone on candidates, more than twice that of Democrats. State House Republicans have a 64 to 34 advantage over Democrats in the 99-member chamber; while Senate Republicans go into the election with a 20-13 majority.
