Voters in Minnesota, Wisconsin, and South Carolina are heading to the polls in the 2026 primary elections, setting up high-stakes legislative showdowns on August 11, 2026. These contests feature significant intra-party friction between progressive and centrist factions, alongside special elections following the death of longtime lawmakers, shaping the landscape for the upcoming midterms.
Here is the math.
The Bottom Line
- South Carolina Senate Special: Appointed incumbent Sen. Darline Graham advances to an August 25 runoff against Rep. Ralph Norman, following the passing of her brother, the late Sen. Lindsey Graham.
- Minnesota Senate Seat: Progressive Lieutenant Governor Peggy Flanagan faces centrist Rep. Angie Craig for the open Democratic nomination, drawing millions in outside political spending.
- Wisconsin Gubernatorial Race: Democratic socialist State Assemblymember Francesca Hong leads the primary field to succeed retiring Gov. Tony Evers, facing competition from Milwaukee County Executive David Crowley.
South Carolina’s Special Senate Showdown
Voters in South Carolina closed their polls at 7 p.m. ET on Tuesday, August 11, 2026, narrowing choices for the Republican nomination to succeed the late Sen. Lindsey Graham, according to Associated Press reports via 270toWin. Sen. Darline Graham, appointed by Gov. Henry McMaster to complete her brother’s term ending in January, will advance to a runoff election.
President Donald Trump endorsed Darline Graham for a full term, yet the compressed campaign featured a large field of experienced candidates. Rep. Ralph Norman (R-S.C.) also advanced to the runoff, setting up a decisive contest scheduled for August 25, 2026, after no candidate cleared the necessary 50% threshold in the initial primary vote.
Minnesota’s Ideological Senate Fight
Meanwhile, in Minnesota, polls set to close at 9 p.m. ET highlight a direct fiscal and ideological clash between the Democratic Party’s progressive and centrist wings. Retiring Sen. Tina Smith’s open seat has catalyzed substantial capital deployment from external political action groups.
Lieutenant Governor Peggy Flanagan represents the progressive platform, running against centrist Rep. Angie Craig (MN-02). On the Republican side, former NFL sideline reporter Michele Tafoya leads polling within a nine-person field, despite lacking the official state party endorsement, as noted by 270toWin.
| State & Office | Key Contenders | Political Alignment | Primary Status |
|---|---|---|---|
| South Carolina Senate (R) | Darline Graham / Ralph Norman | Conservative / GOP | Runoff Set for Aug 25 |
| Minnesota Senate (D) | Peggy Flanagan / Angie Craig | Progressive / Centrist | Active Primary Vote |
| Wisconsin Governor (D) | Francesca Hong / David Crowley | Democratic Socialist / Establishment | Active Primary Vote |
Wisconsin’s Gubernatorial Succession
Wisconsin presents another critical electoral test as Democratic Gov. Tony Evers retires. State Assemblymember Francesca Hong has emerged as the frontrunner, running on a progressive platform centered on expanding the electorate rather than moderating political messaging.
Milwaukee County Executive David Crowley serves as Hong’s primary establishment challenger. Crowley secured the endorsement of Gov. Evers following a fluid primary cycle that included temporary withdrawals and campaign finance complications among rival candidates. Concurrently, opposing Republican strategists have monitored electability metrics closely, anticipating a potential matchup against likely GOP nominee Rep. Tom Tiffany.
