Notable personal detailsMatthew David Klein is a Minnesota Democratic–Farmer–Labor (DFL) politician and physician who has served in the Minnesota Senate since January 2017, representing Senate District 53 (Mendota Heights area). He previously served on the West St. Paul–Mendota Heights–Eagan School Board. Klein is an internal medicine physician and has worked at Hennepin Healthcare and the Mayo Clinic, and he filed to run for U.S. House in Minnesota’s 2nd Congressional District in the 2026 election cycle.
Supports targeted tax relief for working families and seniors (child tax credit expansion, property tax relief, elimination of tax on Social Security) and expansion of refundable credits; opposes tax cuts that primarily benefit the wealthy.
Supports expanding access to affordable care through government-led measures including a public option and allowing Medicare to negotiate drug prices; has championed prescription drug affordability measures and defends evidence-based public health and reproductive health protections.
The candidate calls for ICE to leave and advocates for reducing congressional spending on ICE, framing enforcement reduction and oversight as priorities. He emphasizes seeking justice for Minnesotans whose rights were violated and placing guardrails on federal enforcement actions.
The candidate supports protecting reproductive health and abortion access, stating that decisions about pregnancy, contraception, and abortion belong between a patient and their doctor. He has defended reproductive rights in the legislature while saying he does not personally support elective late‑term abortions and would safeguard against them in practice, framing late‑term procedures as rare and typically for serious medical reasons.
Supports using 100% clean electricity in Minnesota by 2040, treats climate change as a crisis, and backs clean-water protections and tying climate action to labor and union job growth. Served on the state Energy, Utilities, Environment, and Climate committee and has promoted state-level clean energy and environmental protections.
Supports expanded background checks and using public-health data to study and reduce gun violence; backed legislation to allow courts or family to petition to remove firearms from individuals at risk. Emphasizes targeting dangerous individuals rather than blaming all gun owners.
Matt Klein is in the news because Kalshi said it suspended and fined him for betting on his own congressional race on its prediction market. Klein said he placed a $50 wager on himself to win the Minnesota 2nd District Democratic primary. Kalshi said the bet violated its rules and imposed a five-year suspension and a $539.85 fine.
