This is a district that voted overwhelmingly for Clinton (both of them) and Obama (nearly 85%), and is nearly 2-1 latino/a over African-American. The Democratic incumbent is Latina, and because of CA's top 2 primary (where the top 2 vote recipients in the primary, regardless of party move on to the general election), she beat an African-American Dem in the Nov General Election 53%-47%. In the primary, the two Republicans garnered 5.5% and 3.6%. A total of five Democrats received a higher vote percentage than the two Republicans.
