Incumbent Republican Tom Tiffany's decision to pursue the Wisconsin governorship has left WI-07—an open seat with a Cook PVI of R+11, where Trump won by over 20 points in 2024—as a safe Republican hold per Cook Political Report and other forecasters. GOP primary contenders Kevin Hermening ($868K cash on hand) and Michael Alfonso (Tiffany's son-in-law, $732K), alongside Jessi Ebben, dominate fundraising as of late March, dwarfing Democrats Fred Clark ($157K), Ginger Murray ($84K), and Chris Armstrong. With no polls available and primaries set for August 11, trader consensus at 81.5% Republican reflects the district's entrenched GOP advantages and fragmented Democratic field, unchanged by recent developments.
