Democrat Marshall Home, who hopes to challenge attorney Jonathan Rothschild in the Democratic primary for mayor of Tucson, filed his campaign paperwork today.

In a brief interview, Home said he was in the race because of “all the lies and the deceits. How about all the thievery? There doesn’t seem to be any integrity in the government.”

Although he said he would be available for an interview later in the week, Home was not forthcoming about his claims to be a multi-billionaire.

“That’s private,” he said. “I’ve been described as a multi-billionaire. We’ll leave it at that. Why? You can’t accept it at that?”

Home has a major hurdle before he can get his name on the ballot: A lawsuit over his eligibility.

Jeff Rogers, chairman of the Pima County Democratic Party, said operatives are already gathering the necessary information to prove in court that Home is ineligible to run because he doesn’t fulfill residency requirements, given that he was registered as a voter outside the city limits last year.

“I just did a public-records request to get all his voting history so we can file on him,” Rogers says. “He’s not qualified. He’s not a resident.”

Home said he wasn’t concerned the possibility that he could be knocked off the ballot.

“I’m not worried at all,” Home says.
