At the time I posted, heavily Catholic Los Angeles was about 49% yes on Prop 73. LA County isn't nearly as liberal as many counties because it includes very conservative suburbs.
I am sorry to say that LA County is liberal...Slightly less than San Francisco...
LA County is huge...But, there are not many GOP members of Congress in the area. (Drier, McKeon, and Miller. I think Dana Rochabacher represents a small piece of LA County.) Four isn't too many.
