Black candidates make history in Philadelphia's mayoral primary.

Tuesday's off-year elections produced several firsts, including the election of the first woman of color as mayor of Philadelphia, the first Black male as mayor of Colorado Springs, and the first Democratic mayor in decades in Jacksonville, Florida. Republicans also had some successes, including nominating the first Black Republican for governor in Kentucky. The results demonstrate the vulnerability of Republicans in the Donald Trump era, with Democrats flipping the biggest city Republicans controlled in Jacksonville.
