"That outpouring of voter disgust with the car and gas tax hikes should be a message that Sacramento politicians should hear loud and clear," Demaio said.
California's gas-tax was passed by Gov. Jerry Brown. Since November 2017, Californians have had to pay an extra $0.12 for regular, $0.20 for diesel, and beginning January 2, 2018, more on car registration fees.
Supporters of the tax say the money is necessary to fund infrastructure projects and repair deteriorating roads around the state.
Critics, however, say past gas tax funds have gone to other programs and not infrastructure repair. And they expect the same from this tax.
"Governor Brown should have kept his word in allowing voters the final say. They didn't do that. You know why? Because they know that when the voters have a chance to vote ... the voters are going to say 'hells to the no,'" Demaio said.
