Uber Technologies Inc. just won its biggest political battle yet, successfully pressuring the mayor of New York to back down in his fight against the ride-hailing company.

Mayor Bill de Blasio lost this round, but staked out the liberal case against the service: Uber hurts workers, ignores the handicapped, clogs the streets and gouges riders with unfair pricing.
