Philadelphia's Historic Mayoral Race: What to Expect on Primary Day.

The Democratic nomination for Philadelphia's 100th mayor is too close to call, with nine candidates vying for the nod. The winner, who will be elected in November, will inherit a city facing a gun-violence crisis, economic downturn, and staffing shortage. The top contenders include three women, a grocer, and a real-estate magnate. Each candidate has a different vision for how to get Philadelphia back on track, with issues such as poverty, public safety, and city services at the forefront of their campaigns. The race has been the most expensive mayoral campaign in Philadelphia history, with candidates and their allies spending over $30 million.
