MILWAUKEE (AP) -- The four Wisconsin Republicans running for U.S. Senate are remaining cordial in person, even as their television campaigns are getting increasingly negative.
The four candidates appeared Wednesday at a forum in Milwaukee. They took the stage separately for 30-minute presentations.
The four are hedge-fund manager Eric Hovde, former Wisconsin Gov. Tommy Thompson, state Assembly Speaker Jeff Fitzgerald and former U.S. Rep. Mark Neumann.
Each discussed his qualifications, and they avoided any personal attacks.
However, Neumann released an ad Tuesday criticizing Hovde's conservative credentials. Hovde responded Wednesday with an ad accusing Neumann of slinging mud in an attempt to distract attention away from his own poor record.
The four Republicans square off in a primary on August 14. The winner takes on Democratic U.S. Rep. Tammy Baldwin in November.
