The Arizona Secretary of State’s Office investigated nine people who apparently voted in two states during the 2010 congressional elections.

Convictions for voter fraud are felonies, meaning loss of the right to vote, plus up to $100,000 in fines and probation or community service, says Secretary of State Ken Bennett, the state's top elections official.

“Most of what we saw last year with people who had voted twice in two different states in the presidential election of ‘08 were getting a felony, which means they can no longer vote until they take care of that," Bennett said. "They were getting several thousand dollar fine, and community service, and probation."

Last year Bennett sought prosecution of six people for voting in Arizona and another state during the 2008 presidential election. People with multiple addresses can only consider one to be their permanent address for the purposes of voter registration and voting, he said.

It can take years to investigate the cases, because Arizona officials first must compare voter rolls from several states. Bennett said there's a group of 16 states that submit voter rolls to a central database for comparison.

Then state and county election officials must confirm that a single individual did vote twice and rule out anomalies such as someone with the same name, Bennett said.
