Oregon Political Change 1986 to 2010

This post begins a series of posts that will look at the changes in Oregon’s political geography between 1986, the first loss in the current series of Republican Gubernatorial losses, and 2010, the most recent loss in the current series of Republican Gubernatorial losses.
