Congressional candidate Chuck Wooten is facing a lawsuit that seeks to throw him off the ballot long before the Republican primary in August.

Former Tucson mayoral candidate and fellow Republican Shaun McClusky filed the lawsuit, claiming at least 770 of 1,892 Wooten’s signatures should be disqualified.

McClusky said he felt those signing Wooten’s signature didn’t realize he had registered with the GOP two months after he announced he was running for the Congressional District 2 seat.

Wooten said at the time that the party registration issue was an oversight, blaming it on county employees.

A majority of the disputed signatures, McClusky argues, were signed on Republican partisan nomination forms at a time when Wooten was not registered with the party.

If all the 770 signatures are invalidated next week by a judge, it would leave Wooten 145 short of the minimum to qualify as a candidate for Congressional District 2.

That would leave only two other Republican candidates: former Air Force Col. Martha McSally and small-business owner Shelley Kais.

Wooten could not be immediately reached for comment but has already filed paperwork vowing to fight the lawsuit filed by McClusky.

The case is scheduled to go before a Pima County Superior Court judge Wednesday.
