s there anything pop icon Cher can’t do? Nearly 30 years after becoming an unlikely Oscar winner, the diva has taken on the role of hero for Flint, Michigan, residents reeling from a water crisis that has drawn national headlines and put Republican Gov. Rick Snyder in the hot seat.The city of Flint has been coping with a lead-tainted water supply after state officials decided in 2014 to switch the city’s water source from Lake Huron to the an infamously unsanitary local river in order to cut costs until a new supply line was established. Researchers have since determined that the water in Flint is corrosive. Now, the National Guard has been deployed to give clean water to residents and there have been widespread calls for Synder’s resignation.
