Why did the Republican wave stop at the California state line? There will be much speculation about problems with the Whitman and Fiorina campaigns, and some of it will be valid. Nevertheless, much of the answer lies in the makeup of the electorate.
According to the exit poll, Democrats had a 13-point party identification advantage among California voters, compared with an even split nationwide. California voters approved of President Obama’s performance by a ten-point margin, whereas the national electorate disapproved by nine points. It’s just a different kind of state.
