Bay Area “gig-economy” companies fighting state law and court rulings that would force them to classify their workers as employees have pumped another $9 million into their massive push for Prop. 22, California’s most expensive ballot initiative ever.

The total spent in the record-breaking campaign is now nearing $230 million. Prop. 22’s supporters have raised about $208 million while opponents, mostly labor unions, have reported about $19 million, including a blizzard of late contributions topping $3 million.
