We have San Diego voting to the left of IL, NJ and RI. Amazing. Some are already calling that the GOP fails to exist in the Golden State (I am more cautious and will not stand by that).
The top two system is why people are saying that.
Sometimes areas go under one-party control. Where I live in Indiana the Democratic Party effectively does not exist now, their congressional candidate for instance was a joke and supported Trump. I don't see any 3rd party on the horizon in California unless Latinos decide to startup some PRI or PAN clone, Trump got quadruple the votes of Stein in San Francisco.
