Bottlers have settled on the tax-rollback measure they’ll try to get on the ballot: Initiative 1107, which would repeal the Legislature’s taxes this year on soda pop, candy, gum, bottled water and certain food processors, but not beer.

They could start collecting signatures shortly after a court hearing Thursday, said Tim Martin, who leads the Washington Beverage Association. Bottlers expect a judge to decide there whether to amend the ballot title written by the attorney general’s office.

Then they have to sprint: they would have just three weeks to collect 241,153 valid signatures before the July 2 deadline. That would probably be the fastest anybody has ever done it, the secretary of state’s office said.

But the industry has deep pockets. The American Beverage Association has contributed $1.3 million to the cause.

Opponents are no slouches in the money department either. They include the Washington Education Association, Service Employees International Union 775, the Washington Association of Churches and the Washington State Hospital Association, all of which have weighed in on the ballot-title fight.

The pro-revenue groups have formed a committee that may fight the initiative. They’ve raised just $5,000 so far. Spokesman Sandeep Kaushik said the coalition is considering a campaign to convince voters not to sign the petitions.

Bottlers decided not to seek to overturn the tax on beer, another one they were considering taking on. And with time running out, Tim Eyman, another threat to try to roll back some or all of the new taxes, hasn’t pursued any of them yet. His signature collectors are focused on trying to reinstate the requirement for two-thirds majorities in the Legislature to raise taxes.
