The mayor's race has dominated attention in Philadelphia’s Democratic primary, but voters face an arguably harder choice in the City Council at-large race. 27 candidates are running for five seats. 

On this episode of Who’s Running for Philly Mayor, KYW City Hall Bureau Chief Pat Loeb takes a look at the office, and how the wild system for filling it works (or doesn’t) by talking to former two-term Councilman at-large Derek Green, who resigned to run for mayor and then dropped out of the race, and soon-to-retire Council President Darrell Clarke.
