LOS ANGELES  Direct democracy has once again upended California  enough so that the state may finally consider another way by overhauling its Constitution for the first time in 130 years.

Gov. Arnold Schwarzenegger returned home from a White House visit on Wednesday to find the state dangerously broke, his constituents defiant after a special election on Tuesday and calls for a constitutional convention  six months ago little more than a wonkish whisper  a cacophony.

As the notion of California as ungovernable grows stronger than ever, Mr. Schwarzenegger, a Republican, has expressed support for a convention to address such things as the state’s arcane budget requirements and its process for proliferate ballot initiatives, both of which necessitated Tuesday’s statewide vote on budget matters approved months ago by state lawmakers.

“There could not be more of a tipping point,” said Jim Wunderman, chief executive of the Bay Area Council, a business group that moved forward on Wednesday with plans to push for a constitutional convention. “We think the interest is going to grow by orders of magnitude now.”
