Four Republicans filed to run in the district and a party primary was held on February 16. Three made the ballot while an additional candidate, Andrew Dickmann, failed to do so.[1]
On January 11, Pridemore's residency was challenged. On his nomination paperwork, Pridemore claimed to be living at a Hartford address known to be the primary residence of Hartford Mayor Tim Michilak. Michilak is also an employee on Pridemore's campaign staff.[6] The Wisconsin Elections Commission met on January 15 to determine whether Pridemore should remain on the ballot. Neither Pridemore nor the complainant, Steven Hepp, showed up to the virtual hearing and the Commission announced later that day that Pridemore was eligible to remain on the ballot because there is no residency requirement. The Commission spokesman added that if Pridemore was to be elected to the State Senate he would have to have residence in the district 28 days before his swearing-in.[7]
