Biden won a majority of Minnesota Senate districts, but Democrats failed to flip the chamber in 2020

Daily Kos Elections is pleased to present new data from Minnesota breaking down the 2020 presidential results for every district in the state House and Senate—which, unusually, are held by opposite parties.

Democrats went into last year’s election hoping to net the two seats they’d need to retake the upper chamber after four years in the minority, but despite winning more Senate votes statewide, Team Blue only flipped a single seat. More painfully still, Joe Biden carried 37 of the Senate’s 67 seats, a comfortable majority similar in proportion to his share of the statewide vote, which he won 53-45.

Compounding the Democrats’ poor showing, two of the party’s sitting senators, Tom Bakk and David Tomassoni, announced weeks after the election that they would become independents, which earned the duo committee chairmanships from the GOP majority. This state of affairs has given Republicans and their new allies a 36-31 edge in the chamber.

Altogether, six Republicans sit in Biden seats. The bluest of this bunch is SD-26 in the Rochester area in the southern part of the state, where GOP state Sen. Carla Nelson hung on by a 51-49 margin even as Biden was carrying her constituency 54-44. By contrast, Kent Eken is the one Democratic member of the Senate who represents Trump turf: Eken won SD-04 in the northwest part of the state 55-45 while Trump took it 50-48. Tomassoni, for his part, holds a Trump seat, while Bakk’s district went for Biden.

It’s also possible that, but for the presence of a third-party candidate on the ballot in the 27th District in the southern part of the state, Democrats would have won back the Senate. Veteran Democratic Sen. Dan Sparks lost to Republican Gene Dornink 49-44, but Tyler Becvar of the Legal Marijuana Now Party captured 7% of the vote, greater than the margin between the two leaders.

While the cannabis legalization movement is generally associated with the political left, many candidates who ostensibly ran under a pro-weed banner in Minnesota last year received Republican help or espoused right-wing views—including Becvar. But Sparks’ seat would have been a very difficult hold regardless: Trump won it 55-43, so it’s very possible some of those votes for Becvar would have gone to Dornink instead.

Democrats were able to maintain their majority in the Minnesota House, but their edge slipped from 75-59 to 70-64. Biden took 72 districts to Trump’s 62, and though crossover voting benefited Republicans overall, the GOP’s advantage wasn’t as large as it was in the Senate on a proportional basis: Six House Republicans won Biden seats, while four Democrats took Trump districts.

The Democrat with the reddest turf is Paul Marquart, who earned his 10th term 53-47 even as Trump was romping to a 58-39 victory in his HD-04B. (In Minnesota, two state House districts are nested within one Senate district, and Marquart represents half of Eken’s aforementioned 4th Senate District.) Marquart’s Republican counterpart is Keith Franke, who had lost reelection in 2018 but reclaimed HD-54A by a 51-48 margin despite Biden’s 54-43 victory in his suburban Twin Cities constituency.

Minnesota is one of just two states where the same party doesn’t hold both houses of the legislature; the other is Alaska, where Republicans have nominal majorities in each chamber but the House is run by a coalition of Democrats, Republicans, and independents.

This state of affairs makes it extremely unlikely that the Minnesota legislature and Democratic Gov. Tim Walz will agree on new congressional and legislative maps. This deadlock would mean that the courts would take over redistricting, which is exactly what happened a decade ago—and each of the last several decades.

Once new maps are implemented, each party will immediately have another chance to try and win both chambers. The entire House is on the ballot every two years, while the Senate is up in years ending in 0, 2, and 6, meaning that senators who won election in 2020 are currently serving two-year terms but will run for four-year terms next year. (This system, known as “2-4-4,” is used in eight states.)
