Indiana Gov. Mitch Daniels (R) is throwing his support behind former Wisconsin Gov. Tommy Thompson's (R) Senate bid, the latest good news for Thompson and latest sign that Daniels has no problem bucking Tea Party groups.
Daniels will attend a Milwaukee fundraiser with Thompson on June 25, according to an invitation to the event obtained by The Hill.
Thompson faces a crowded primary field that includes former Rep. Mark Neumann (R-Wis.), who has the backing of a number of national Tea Party-aligned groups including the Club for Growth. Self-financing businessman Eric Hovde (R) and Wisconsin state Assembly Speaker Jeff Fitzgerald (R) are also in the race.
Daniels is the latest governor or former governor to back Thompson, who was endorsed by former Florida Gov. Jeb Bush (R) on Monday. A half dozen other former governors have also endorsed him. He is looking increasingly secure in his primary bid since Hovde's entrance into the race, which a few Wisconsin Republicans have said has further fractured the anti-Thompson vote.
