It was President Obama's fault.
No, I haven't thrown in with the Obama-haters who pin blame for everything from Ebola to the polar vortex on the Democratic president.
I'm reporting the takeaway from a fascinating analysis of the 11 DFL defeats on Nov. 4 that flipped control of the Minnesota House to the GOP, giving that party a 72-62 edge in 2015-16. The analysis suggests that Obama's unpopularity had a lot to do with results in those 11 districts.
It's the handiwork of Brian Rice, the Minneapolis attorney/lobbyist/born-and-bred DFLer and election math whiz. He examined the House results in every presidential midterm election for the past 60 years — 16 in all — and scored what happened to the state House caucus allied with the president's political party in each of those elections. (Before 1974, those caucuses used the nonpartisan names Liberal and Conservative. Rice took those terms as proxies for Democrats and Republicans, which they were.)
In 14 of those 16 elections, the caucus associated with the president lost seats. The two exceptions were in 1990, when President Bush the First was basking in the glow of winning the Cold War and gearing up for the Gulf War; and in 2002, when President Bush the Second was on a post-9/11, pre-Iraq War footing and the DFL was in disarray after the death of U.S. Sen. Paul Wellstone. The GOP gained one House seat in 1990 and 12 in 2002.
Cast aside those two exceptions, and consider the number of state House seats typically lost by the president's party in midterm elections. They ranged from 6 to 37. The average: 17.
By those lights, this year's swing of 11 seats doesn't seem so stunning. Neither does the fact that 10 of the 11 districts that switched from DFL to GOP are in Greater Minnesota — not when one considers the president's popularity pattern in this state.
A Survey USA poll conducted Oct. 27-30 in Minnesota (which Obama carried in both 2008 and 2012) found that his approval statewide had slipped to 40 percent. That's well into the political peril zone.
