Stanislaus flipped to Trump, might flip back, but I doubt it
Everyone knows of Orange County.
Imperial was not one of the strongest by the standards of the state, despite the demographics.
Stanislaus flipped back to Hillary a few days ago, just as I predicted in another topic. The late count in the Central Valley tends to heavily favour Democrats, hence Ami Bera's relatively comfortable reelection. (On the other hand, they need to put a strong effort in to flipping CA-10, which really shouldn't be that hard.)
I don't know why you point out Imperial County. I think Hillary's 41%+ win in the county is probably the biggest win for any Democrat ever, although I've only seen results back to 1920.
As for Orange County, I fully agree. I had a strong feeling she would win prior to the election, but her current margin is far more than I ever could have imagined. On a good night, I was expecting something like 49-46 for Hillary. She's up in Orange County by a 51-43 margin, with 122k ballots left to count. That's a massive historic swing.
Elliot County, cough cough.
