Seeking to set the terms of negotiation before next week’s vote to repeal the county’s beverage tax, Cook County Board President Toni Preckwinkle introduced a proposed $5.36 billion budget for fiscal year 2018. The keystone of the budget, an estimated $200 million in revenue from the sweetened beverage tax that took effect only a month ago, seemed likely to be repealed in vote scheduled for next week as the Board’s Finance Committee Chair, and Preckwinkle’s most stalwart ally, Comm. John Daley (D-11), announced plans Thursday afternoon to support the repeal of the tax.
