Take a look at how Contra Costa could be redistricted by clicking on the links above. As you can see, Lamorinda is split in this visualization: with parts of Orinda in a district with Berkeley through West Contra Costa (now Asm. Joan Buchanan) and another part of Orinda in a district with parts of Alameda County (now Asm. Mary Hayashi).
Lafayette and Moraga would find themselves in a district going down through Danville and San Ramon into the Tri-Valley (now Asm. Joan Buchanan). That latter district could be one of the state's battlegrounds: with Democrats holding a 40-35 percent registration advantage.
The Redistricting Commission is scheduled to release its draft lines on Friday, June 10. Needless to say, that will prove an important day in California politics–and it may even have an impact on the state budget negotiations as legislators see who their new voters may be.
