Debbie Arnold, a former legislative aide to Republican Assemblyman Sam Blakeslee, is formally launching her campaign for Jim Patterson's 5th District county supervisor seat.
In an e-mail to supporters, Arnold said she planned to make the announcement on Friday, Jan. 11, at 12:30 p.m. on the steps of the old courthouse in San Luis Obispo.
Arnold, married to SLO County Farm Bureau at-large director Steve Arnold, was an aide to former Supervisor Mike Ryan. Before that, she owned and operated an Atascadero preschool for 17 years. The couple raises cattle and owns Pozo Valley Vineyard.
When she left Blakeslee's office in October, Arnold announced plans to open a SLO chapter of a group she called Women for Agriculture, Open Space and Workforce Housing.
Arnold did not respond to calls about her announcement by press time.
Patterson won the seat from Ryan in 2004. This will be his first re-election campaign.
The nonpartisan primary is June 3.
With her announcement, all three open supervisor seats will have challengers. Paso Robles Mayor Frank Mecham is challenging Harry Ovitt in the 1st District and Cal Poly lecturer Adam Hill is challenging 3rd District Supervisor Jerry Lenthall.
