A series of pivotal primaries across the Upper Midwest on Tuesday, August 11th, 2026, marked significant wins for the Democratic Party’s progressive wing, with Minnesota’s lieutenant governor Peggy Flanagan securing the Democratic nomination for the U.S. Senate. Flanagan defeated congresswoman Angie Craig in a contest that underscored the ongoing struggle between progressive and moderate factions within the party.

The Minnesota Senate primary centered heavily on immigration enforcement, a contentious issue following a crackdown by the Trump administration earlier this year that resulted in deadly and destructive outcomes. Flanagan’s victory is seen as part of a broader anti-establishment wave among Democrats, where progressive candidates have been toppling moderates.

In addition to Minnesota, other primaries in the Upper Midwest delivered key wins for progressives, though a major test remains in the battleground state of Wisconsin, where the race is still too close to call. Meanwhile, Ilhan Omar secured another primary victory in her Minneapolis-area district, reinforcing progressive strength in the region.

The 2026 midterm elections will be crucial in determining control of the U.S. House and Senate, shaping the legislative agenda for President Donald Trump during the final two years of his term.
