Forty years after first taking the oath as governor of California, Democrat Jerry Brown was sworn in to an historic fourth term Monday, proposing sweeping changes to address global climate change while offering a measured approach to targeting the state's long-term financial liabilities. Brown has in the past used the speeches to make promises. In his third inauguration address in 2011, at age 72, he pledged not to raise taxes without a vote of the people, and to "speak the truth" about the state's financial condition, which at the time was a $27 billion deficit. Four years later, California is anticipating multi-billion dollar surpluses after voters approved Brown's sales and income tax increases. "While we have not reached the Promised Land, we have much to be proud of," he said.
