One thing to keep in mind about Orange county is that it is surprisingly working class. Sure it has places like Irvine, the south coast and the beach cities but it also has places like Santa Ana and central Anaheim. There are also lots of middle class areas like La Habra, Buena Park, Garden Grove etc that don't fully fit the mold of affluent and well educated suburbs. It is a decidedly middle class area full of non-whites that polls are suggesting are fleeing from Biden. This is actually a decent poll for him considering all that.
Yeah the race and ideology crosstabs look quite good for Biden considering he's an unpopular D running for reelection. If he actually wins Orange County by 8% that's a minimal R swing from 2020. (Not that I expect the R swing in CA to be particularly strong there).
