Peggy Flanagan is running for the nomination for an open Senate seat against centrist Democratic Rep. Angie Craig. Left-leaning candidates have consistently won primaries, capitalizing on Democratic voter frustration at party leadership. President Donald Trump won Wisconsin in 2024 and its state legislature has long been in the hands of the GOP, but Democrats have been bullish about reversing that trend. The winner of the Democratic primary will face Republican Rep. Tom Tiffany in November. In 2020, Trump tried to claim Wisconsin despite it being won by Joe Biden, only to be blocked in part by Evers.
