The City of LA is not the whole of Southern California. You have Orange County, San Diego, and other places as well. There are plenty of Americans (of all heritages) who will fight this...whether the pols will or not at this point. They just need to be energized and I believe that is finally happening on this issue now.
I hope you are right. I think the tipping point has already been reached in Southern California (all the way to SF maybe). I don't think they will fight it.
