SACRAMENTO, Calif. (AP) – California delivered on its reputation as a testing ground for liberal ideas as lawmakers wrapped up a legislative session that extended the nation’s most ambitious climate change programs, raised the minimum wage to $15 and toughened gun laws. Lawmakers advanced top priorities for the labor, environmental, gun-control and anti-tobacco movements. But Democrats who control both houses of the Legislature failed to address some of the maddening challenges afflicting Californians’ daily lives, including skyrocketing housing costs and crumbling roads. Democrats celebrated their victories and said the nation’s largest state is a model for other states to emulate. The changes left Republicans and businesses frustrated with what they see as a crushing load of new regulations that include extensions of California’s landmark climate change law and a new cap on methane emissions.
