I still hope for a Fiorina upset. Boxer is one of the worst senators the Senate has seen. The Central Valley is going to give Fiorina a landslide margin. The polls might be underestimating Republican turnout since California hasn't had a competitive senate election in about 12 years.
California elections aren't decided in the central valley. How is Fiorina doing in suburban LA county? That is what will decide this election.
She is a lock in Orange County and the Inland Empire. San Diego is probably leaning strongly towards her, as are Ventura and San Luis Obispo. It will actually probably come down to whether or not she can get around 40% in suburban parts of the Bay Area that puts her over the top.
Yes, she is a lock in Orange County, IE as well as the Central valley. That is why the race is even close to begin with. You are absolutely right that she will have to do well in certain parts of the bay area like Contra Costa county and Solano. And she will at least need 37-38% out of Santa Clara. LA county suburbs are the other battleground. CA-36, 29, 27 etc. These are the CD's where she needs to put up respectable numbers in order to win.
