If we end up with a CA-31 2012 situation here then I will probably blow a gasket.
We're talking about a statewide California race here. Republicans can't win.
Sure, but if enough big name Democrats siphon votes from eachother, two Republicans could eek out of the primary.
Won't happen, Republicans usually get around 40% of the vote in California. For that situation to occur, two Republicans (and only two) would both have to get around 20%, and there would have to be 4+ Democrats who split the vote evenly.
It would be hilarious if that would happen, though.
