Philadelphia's Expensive Mayoral Race: Implications and Predictions.

Philadelphia Democrats are set to choose their nominee for the city's 100th mayor in a historic election that could see the first woman and Asian American elected to the position. The race has centered on education and public safety, with progressive candidate Helen Gym gaining support from grassroots liberal activist groups and receiving endorsements from Bernie Sanders and Alexandria Ocasio-Cortez. Other contenders include Cherelle Parker, Rebecca Rhynhart, Allan Domb, and Jeff Brown. The winner will become an important national political player among Democrats and face the only Republican nominee in the fall.
