 Its goal is to implement approval voting in at least 5 cities with 50,000 people by 2022.CES argues that approval voting is superior to other proposed electoral reforms, such as ranked choice voting; it says approval voting will elect more consensus winners, which it contends traditional runoffs and instant-runoff ranked methods don't allow, because they eliminate candidates with broad support but low first-preference support.CES was founded in 2011 by Aaron Hamlin and Clay Shentrup.
