Gidwitz's comments came one day after the state's Republican leadership chastised Gidwitz for airing a negative ad about Topinka. The party claims the ad violates a "code of conduct" promoted by state GOP chairman Andy McKenna to keep campaigning clean.
Gidwitz accused McKenna of working for Topinka. Poll numbers show Topinka is the front-runner in the Republican primary race.
Gidwitz denied his TV ad was negative and said it is fair game to question someone's record.
