I charted out the recent election’s seniority changes to Minnesota’s delegation in the US House of Representatives:
The Oberstar to Cravaack flip in the 8th district certainly stands out. That was the only seat to change hands in Minnesota this year, so all other seats gained in seniority. Colin Peterson, in the 7th, gained the least (71st to 60th in seniority), but he also has the fewest seats to gain.Peterson could reach Oberstar’s seniority level in less than 2 decades at the rate he’s going.
Wikipedia has seniority data going back to the 103rd Congress. Plotting that data over time lead to this:
Previous spikes is lost seniority were caused by Ramstead retiring (3rd), Gutknecht losing (1st), Sabo retiring (5th), Vento dying (4th), Minge losing (2nd), and Tim Penny retiring (1st).
Averaging out the seniority of Minnesota’s US House members, ads a 9th line to the chart:
Which shows that Minnesota has been steadily losing clout in Washington since 2001.
Since at least 1993, the 6th District has consistently been a below average seat for seniority. Averaging out the seniority of each house seat since 1993 looks like this:
Perhaps Bachmann will change that record overtime by getting reelected again and again? It seems like she may have other plans, so the 6th may return to the cheap seats sooner than later.
