Scott Bruun! OLCV, say it isn't so!

Could someone from OLCV please explain the endorsement of Scott Bruun (25% OLCV score in the 2005 session)? In addition to the atrocious record on the environment, there is also a tactical issue to consider. Sure, groups like OLCV and Sierra Club work under the premise of non-partisanship but the Republican Party for the last 25 years has done absolutely nothing for the environment and has actively worked dismantle the very democratic institutions that we rely on in our work protect the environment from big polluters and greedy developers. In practice, it’s very difficult to be non-partisan. Considering that the GOP majority in the State House is nothing but a machine that pumps out one bad environmental bill after another, why would OLCV make an endorsement that will help preserve that majority, especially for someone with such a poor environmental voting record?
