Brandon Johnson, a county commissioner and teachers’ union organizer who called for a vast expansion of social programs in Chicago, as well as new taxes, was elected mayor of the country’s third-largest city on Tuesday, according to The Associated Press.

Mr. Johnson’s victory over Paul Vallas, a fellow Democrat with far more conservative views on crime and education, revealed voters rejecting the tough-on-crime politics that have become a staple of municipal elections in recent years and instead embracing a decidedly progressive vision for a city still working to emerge from a pandemic malaise.
