Even though it is Labor Day weekend and the state has entered into a historic period without a budget, good news came Sunday for public transportation advocates and well-wishers. AB2321, the bill that would allow Metro to put a half-cent sales tax increase on the November ballot that could raise $30-40 billion for transportation projects over the next 30 years, took another critical step: the state Assembly passed it. That means two more steps until Los Angeles has higher taxes, but better public transportation: governor Schwarzenegger must sign the bill (he promised not to sign any until the budget mess was over, but he is wishy washy) and the people of LA County must vote for it.
