Most congressmen face a big struggle to first get elected, and then stay in their jobs for a considerable period of time. John Dingell, for example, holds the all-time record. He’ll have served fifty-six years before this year is over.
John Conyers has been there forty-six years.
Dale Kildee and Carl Levin have been in Washington more than thirty years. But on the other hand, the seventh district, which spans southeast Michigan’s border with Ohio, has been about the most volatile congressional district in the nation over the last decade.
Starting in two thousand and two, the seventh district has elected a different congressman in every election. Tim Walberg, who holds the job now, won in two thousand six; lost in two thousand eight, and won his old seat back in two thousand and ten.
Odds were that he would have faced another stiff challenge next year, possibly from one, or both, his two main rivals in the recent past. Fellow Republican Joe Schwarz beat Walberg in a primary in two thousand four, and then lost to him two years later.
Democrat Mark Schauer ousted Walberg from Congress in two thousand eight, and was ousted by him last year.
But this year is a redistricting year. Republicans control every branch of government, and one of their top priorities was to draw the lines so as to make re-election safer for their side’s incumbents.
In the case of the Seventh, they replaced Calhoun County, at the west end of the district, with Monroe County, at the eastern end. The counties are almost the same size, and both usually, but not always, vote slightly more Democratic than Republican.
