The impact of the Franken news is bound to reverberate across the ballot in Minnesota, a state that had been trending unmistakably in the GOP’s direction. As it is, the state is holding a wide-open governor’s race, and half of the state’s eight House seats—two Democratic, two Republican—are up for grabs in next year’s midterms. The only constant is Sen. Amy Klobuchar, whose sky-high job-approval ratings make her a safe bet for reelection.

Minnesota nearly became one of the “blue wall” states that flipped to Donald Trump last November. Hillary Clinton carried the state by a mere point, a big falloff from President Obama’s 8-point romp in 2012. The cultural crosscurrents in American politics are vividly reflected in the state: two Obama-voting Congressional districts flipped to Trump, while one swing seat moved in a Democratic direction.

The Republican-held House seats are endangered because they’re nestled in affluent suburbs that are disillusioned with the president, while the Democratic seats are in rural enclaves where Trump made massive gains in last year’s election.
