Former city council president, state senator and auditor general Jack Wagner has picked up mayoral endorsements from four unions representing about 60 percent of the city's 3,000 workers, including its police officers and firefighters.
The 65-year-old politician is one of five Democrats seeking the nomination to replace Mayor Luke Ravenstahl, who is not running for re-election.
City Councilman Bill Peduto and Controller Michael Lamb are seen as the other leading Democrats.
City Council President Darlene Harris dropped out of the race Wednesday, citing family commitments. State Rep. Jake Wheatley and Abdula Jamal Richardson, a political novice and community organizer, are the other Democrats running.
Josh Wander, a consultant and state constable, is the only Republican running in a city that hasn't elected a mayor from that party since the Great Depression.
