Tina Smith was appointed to Minnesota’s Senate seat in 2018 after Al Franken’s resignation and won election in her own right twice since. She was never the most prominent name in Minnesota Democratic politics — that distinction has long belonged to Amy Klobuchar — but she was a reliable, workmanlike senator who didn’t generate the kind of controversy that attracts well-funded opponents. Her retirement removes that quiet structural advantage.
Minnesota has been trending in the wrong direction for Democrats at the presidential level. Trump came within 1.5 points of flipping the state in 2024 — unthinkable just a decade ago when it was safely blue. The Iron Range, once the backbone of DFL politics, has been hemorrhaging Democratic support for a decade as the coal-and-steel identity of the region clashed with the national party’s environmental positioning. The Minneapolis-St. Paul metro now carries the entire Democratic coalition on its back.
The Democratic Primary
The DFL bench is real. Former Governor Tim Walz is a familiar name — though his role as Kamala Harris’s running mate and the outcome of 2024 may complicate his political positioning if he were to run. Lieutenant Governor Peggy Flanagan is a prominent figure with strong progressive credentials and would make history as the first Native American senator. Other names from the Minnesota House and state party apparatus could enter as well.
The primary will test competing visions for how to win Minnesota statewide: run a coalition-expanding candidate who can appeal to the Iron Range and rural areas, or energize the metro base and run up the score in Hennepin and Ramsey counties.
The Republican Opportunity
Republicans see this as one of their best opportunities to finally flip a state they’ve been chasing for years. A strong nominee — potentially a statewide official or prominent business figure — could force Democrats to spend heavily in a state they’d rather take for granted. The GOP will spend aggressively on messaging to rural Minnesota and in the suburbs north of the Twin Cities that have been shifting.
What to Watch
Minnesota has not elected a Republican senator since 1978. That streak may be tested in 2026 if the presidential trend holds and Democrats can’t find a candidate who speaks to the working-class Minnesotans the party has been losing. An open seat in a trending-purple state is exactly the scenario Republicans have been waiting for.
