I'm a native San Diegan. Pukin Dog "gets it."
The LA Times article specifically mentioned the Dem primary between Filner vs Vargas in the 51st district. Filner is considered part of the Waxman-Berman Jewish-Black Dem machine. The new Latino activists have broken with that alliance, as evidenced by Villaraigosa's win in LA.
The old Chinese proverb certainly rings true; conservatives generally think they are the big losers from amnesty, but the Jewish-Black block have just as much to lose to the new Latino majority.
