Opponents of a proposed sugary drinks tax demonstrate Wednesday, May 4, 2016, outside City Hall in Philadelphia. Former New York City Mayor Michael Bloomberg has contributed an undisclosed sum to a nonprofit group starting an $825,000 ad campaign in support of a three-cents-per-ounce tax on soda and other sugary drinks. The American Beverage Association has already spent more than $1.5 million on an anti-tax campaign. (AP Photo/Matt Rourke)
