Is Linn County, Iowa, urban or rural? Who can say when even federal agencies disagree.The population is concentrated in Cedar Rapids, which has long dominated county government as well. But rural Linn Countians stand a good chance of gaining stronger representation this year. After a push from rural residents and the local Farm Bureau, the county Board of Supervisors has been expanded from three to five seats; and representatives will be chosen by district (though district lines were not drawn so much to the Farm Bureau's liking).Adam Belz's piece for the Cedar Rapids Gazette lays out some of the conflicts in this betwixt locality. "The primary election on Tuesday and the November general election mark a sea change in Linn County politics," he writes, "a change that is rooted in the complicated relationship between the county's rural and urban interests."The beat – and the discussion – go on in Belz's blog.
