Among all Californians, residents are more likely to favor (50%) than oppose (45%) same-sex marriage for the first time in the PPIC Statewide Surveys. Support among all adults has never surpassed 45 percent since the question was first asked in January 2000. There are clear partisan divisions: majorities of Democrats (64%) and independents (55%) are in favor, and most Republicans (67%) are opposed.
There is much more consensus on the issue of gays and lesbians in the military. In the wake of Obama’s announcement that he would like to repeal the federal "don’t ask, don’t’ tell” policy passed in 1993, 75 percent of Californians say that gays and lesbians should be allowed to serve openly in the military.
The study also found Meg Whitman leads Democratic candidate Jerry Brown, 44 percent to 39 percent, this isn't good. However, Brown has not begun his campaign and Whitman has spend a lot of money flooding the airways the last few months. We cant afford to let her win either.
