The report ends with this these thoughts about 2012 and California's political future:
California may tend to vote for Democratic presidential candidates , but many places around the state espouse views that fall to the right of the Democratic Party’s typical positions. In fact, only the Bay Area is home to extraordinarily large numbers of people who hold opinions associated with the Democratic Party.
This could signal an opportunity for Republicans. Moderate Liberal and Conservative Liberal places contain half the state’s population and seem sympathetic to many conservative positions—yet they tend to support the Democratic Party. Still, altering this status quo could prove difficult. The small number of liberal Republicans in every part of the state implies that the party's electoral coalition is ideologically solid—but that may also make the party resistant to expansion efforts. Only time will tell.
Regardless, California’s 2012 election promises to be exciting and unpredictable. Given the inherent tensions between ideology and partisanship in much of California, the political geography that emerges after the election could look very different from the current landscape.
Very interesting stuff! I encourage you to read the entire thing, "California Political Geography," by Eric McGhee and Daniel Krimm.
