According to the information from the article in post #55, he “went to the polls in May 2009.” If his registration expired in 2006, that would be problematic.

State law requires Secretary of State candidates in a primary election to have been a registered member of their party for at least three months prior to running. Also, in the year before filing a declaration of candidacy, they can’t have been registered with any other party.
Dunn freely admits to being a “recovering non-voter” who made his voice heard at the polls for the first time in last May’s special election on ballot measures. He has said that he registered shortly prior to that election—as a Republican.
That checks out. OC voter registration records show Dunn registered as a Republican on March 17, 2009. He then voted absentee in the May 19 election.
