Democrats are down as well. The trend toward independents marches on.
I’ve been a registered decline-to-state for some time now, absolutely unable to attach my name to a party which continually ignores people like Bruce Herschensohn and Tom McClintock in favor of such disasters as Schwartzennegger. Thanks to our election rules, I am given a choice of primary ballots, R or D, so my vote still counts (well, makes an unnoticed statement really, since the Presidential/VP candidates are determined long before we vote).
And as to “California is rapidly becoming a state dominated by recent immigrants,” well. that’s how California got this way, only those the earlier immigrants were from other states, bringing their baggage and preconceptions of what California was with them. Having trashed their sandbox, they and/or their children are off to other states.
Just for kicks, you might ask the older, say over 25, incoming “Californians” where they were born and raised.
