An analysis by inewsource has found that the San Diego County Democratic Party used a part of California’s campaign finance law called “member communications” to spend hundreds of thousands of dollars on one candidate. The law allows both Republican and Democratic parties to funnel money into San Diego races despite efforts by local governments to curb party spending.

To gather the data on member communications in San Diego County, inewsource compiled more than 3,400 transactions by hand. These transactions were listed on more than 120 financial reports the local parties filed with the Secretary of State’s Office since 2011.
