Gov. Jerry Brown vetoed his own party’s budget today, less than 24 hours after Democratic lawmakers sent him a majority-vote plan balanced with risky solutions. The Democratic governor said during his campaign and throughout this year he would not sign a budget filled with “gimmicks,” though he suggested earlier this week he had relaxed that stance. In a letter to lawmakers, Brown said the Democratic plan is “not a balanced solution. It continues big deficits for years to come and adds billions of dollars in new debt. It also contains legally questionable maneuvers, costly borrowing and unrealistic savings. Finally, it is not financeable and therefore will not allow us to meet our obligations as they occur.”The governor did praise Democrats for “valiant efforts” in making painful cuts. He blamed Republicans for blocking real solutions.
