Big Sky Political Analysis is a blog maintained by political scientists at Montana State University. At the moment, it’s especially useful for following the Tester-Rehberg Senate race — e.g., here. I was remarking to someone last week that political science bloggers have a real opportunity to have an impact by writing about state politics and building relationships with in-state journalists (e.g., as in the Kansas politics blog I mentioned earlier). Big Sky Political Analysis is another excellent example.
