Gov. Jerry Brown got mad and one year later has gotten even with the oil lobby. It’s a textbook example of what can happen in a representative democracy when a leader is willing to settle for realistic goals. It’s what results when one doesn’t get too greedy and agrees to compromise. It’s also symptomatic of one-party control. Dominant Democrats in Sacramento hang together more often than not, and that produces victories when only a simple majority vote is required. And that’s usually. Republicans these days are mostly irrelevant in California’s Capitol.
