The collapse of budget negotiations leaves a temporary vacuum as state leaders decide where to head next. This much is known; the state needs to solve a reminaing $15.4 billion deficit, and lawmakers have exhausted many options in the realm of spending cuts and fund transfers. Gov. Jerry Brown and legislative Democrats have given up on a June tax election. But they have not abandoned their desire to solve most of the remaining deficit with additional tax revenue. Republicans say they remain opposed to taxes, though they have not provided a complete alternative.
