From the SDCDP:
As of this month, Democrats have regained the lead in San Diego County's voter registration, erasing a 5,000-voter advantage the Republicans held as recently as September.
Last year Meg Whitman dumped hundreds of thousands of dollars into voter registration during her failed gubernatorial bid, boosting the Republican rolls with fraudulent and financially incentivized registrations. But the county's "blue" tilt since then suggests that the underlying political and demographic trends favor Democrats.
Registration numbers for the two parties have hovered within a razor-thin margin of each other countywide since the 2008 elections. With an eye toward greater potential in the 2012 presidential election year, the County Democratic Party is currently developing an expanded voter registration program in its updated strategic plan.
More immediately, volunteers are needed to register Democrats at events this summer, including the Juneteenth festival (June 18), naturalization ceremonies in San Diego (June 22) and Chula Vista (June 24), and LGBT Pride (July 16-17). To sign up for a shift, email firstname.lastname@example.org.
