Last month, a New York judge struck down New York City’s ban on sugary drinks in containers larger than 16 ounces. Soon after, former vice presidential candidate and reality television star Sarah Palin thrilled a crowd at the Conservative Political Action Conference by pausing her speech to sip from a Big Gulp. Then, freshly-minted Texas U.S. Sen. Ted Cruz proposed a largely ceremonial “Big Gulp Amendment,” which would keep the federal government from limiting soda size, while Mississippi’s governor signed into law a bill that prohibits local governments from regulating sugary drinks. New York’s mayor, Michael Bloomberg, has taken heat for pushing for the soda size ban, though history may treat him more kindly than have conservatives. Science may, as well.
