In 2017, Melvin Carter was elected the first African-American mayor of St. Paul. He got 51 percent of the first-choice votes, easily outdistancing four major challengers. Now he’s grappling with how to meet the high expectations of city residents, who are worried about a crime rate that rose 10 percent in 2017, and making ends meet in a city in which one in five live in poverty. Carter is pushing for a $15 minimum wage, college savings accounts for every child, and higher property taxes. Residents are watching to see whether he can broaden the job base, boost student achievement, and make the city safer.
