Exits indicate that McCain will win the overall California vote.  Obviously, how it breaks down district by district will determine whether Romney has been utterly humiliated or simply beaten.  McCain is running strongest in central California, the Bay area and L.A. County, while Romney does best in southern California and the northern coast.  McCain’s margins in both L.A. County and the Bay area are larger than Romney’s in his best areas, which means that McCain may be more competitive in Republican-held districts than some expected.

P.S.  CNN has already called California for McCain.  So much for Romney’s late polling surge.
