Sea change?
I would not read too much into the rejection of the Los Angeles sales tax increase. If that had been a general election with all of the low information voters driven to the polls by union thugs the sales tax increase probably would have passed. San Diego rejected a similar sales tax increase in a non general election, however in the next general election a Marxist (Bob Filner) was elected mayor because the union goons got the numbskulls to the polls.
What was it - like 20% of the people voted. These scumbag pols will now put it up again for a vote but they will make sure that they have their useful idiots out to pass it. Their cancer will continue until the patient (establishment) is dead.
