JOSH KRAUSHAAR: The Franken Factor In Minnesota.

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.

Democrats are most bullish about ousting freshman Rep. Jason Lewis, a provocative conservative talk-show host who surprised health-care executive Angie Craig in a closely contested race last year. Trump’s narrow victory in the St. Paul-area district carried Lewis to reelection, but he won’t be able to count on strong GOP turnout the second time around. He’s facing a rematch against Craig next year. If Democrats want to take back a House majority, they’ll need to win this seat.

The biggest bellwether in the country is the neighboring Third District, where Rep. Erik Paulsen has been one of the most battle-tested Republicans in Congress. He first won this swing Twin Cities seat in a 2008 Democratic landslide, and routinely wins reelection by sizable margins. He ran a whopping 16 points ahead of Trump in last year’s election despite facing a highly touted Democratic recruit. This year he’s expected to face Democrat Dean Phillips, a wealthy founder of a gelato company, who emerged as an early party favorite.

What makes Minnesota’s politics so interesting is that Republicans have a rare opportunity to make inroads into some traditional Democratic strongholds, as well.

Trump’s inroads was the political story of 2016, but even then it was a near-run thing for Trump in the blue states that put him over the top. Whether Trump and the Republicans can build on that success or whether it proves to be a one-time thing will likely be the political story of 2018.
