As BuzzFeed reported today, fast-food workers will walk off the job in Charleston, S.C. and nearby cities Sunday, before converging on the Democratic presidential debate that evening with thousands of homecare, child care, and other underpaid workers to challenge candidates to “come get our vote.”  USA Today noted that the strike marks the first of an unprecedented wave of walkouts and actions calling for $15 and union rights that will hit this primary season to hammer home to employers and candidates that the nearly 64 million Americans paid less than $15 an hour are a voting bloc that cannot be ignored.
