The race for Pima County Supervisor District 1 may turn out to be a tough primary battle for long time incumbent Ann Day. She is facing a credible challenge from local businessman Joe Higgins. Sources tell us that he has secured Sherry Potter to help with his campaign. Now Seeing Red AZ is reporting that Day has lined up Lincoln Strategy Group to run her campaign. If this is true look for the race to get nasty as the Day team goes negative. We are not sure that strategy will work very well since Higgins is planning a positive campaign focused on the issues important to district 1.
