The snack food giant Mars has become the latest corporation to publicly cut ties with the right-wing American Legislative Exchange Council, or ALEC. ALEC has come under sustained public protest for backing a number of controversial measures, including the so-called “Stand Your Ground” gun laws, which critics say enabled the killing of Trayvon Martin. Mars is the maker of Skittles, the candy that Travyon Martin was carrying when George Zimmerman shot him dead. Mars’ severance of its ties to ALEC follows that of other companies including McDonald’s, Coca-Cola, Pepsi and Kraft.
