The 2027 Minnesota U.S. Senate special election stems from Amy Klobuchar’s resignation after her 2026 gubernatorial victory, creating a vacancy for the remainder of the term ending in 2031. Minnesota has not elected a Republican to the Senate since 2002, and recent DFL performance—including a 2026 blue wave that delivered wins in the open Senate seat and other statewide races—underpins the Democratic Party’s 87.5% implied probability. An interim appointee selected by Klobuchar or outgoing Governor Tim Walz will serve until the November 2, 2027, general election, with the August 10 primary determining major-party nominees. Multiple prominent DFL figures have been floated as potential candidates or appointees, leaving individual names at even odds pending clearer primary fields. Republicans face structural challenges in the state but could benefit from national attention in an off-year contest.
