Rep. Tammy Baldwin (D-Wis.) came out the winner in the second quarter fundraising battle in the Wisconsin Senate race, bringing in $2.2 million.
Baldwin raised significantly more than her four GOP rivals, who are competing against each other for their party's nomination. The primary election is set for Aug. 14.
Former governor Tommy Thompson, who has long been the frontrunner in the race, brought in $834,000, according to WisPolitics. Former congressman Mark Neumann -- who has the support of high-profile conservative lawmakers and the deep-pocketed Club for Growth -- brought in $733,000. Businessman Eric Hovde raised nearly $240,000, although he is a millionaire and is self-funding his race. State Assembly Speaker Jeff Fitzgerald has not yet released his fundraising figures.
Hotline's Sean Sullivan notes that Thompson's fundraising total is "disappointing," writing, "A former four-term governor and cabinet secretary who has spent his post-government career on the lobbying circuit should be able to crack $1 million for a Senate race."
