A former city councilman held an early lead in Tuesday's Democratic mayoral primary over a millionaire business executive and two congressman.
Michael Nutter, who gave up his council seat to run for mayor, had 33 percent of the vote with 42 percent of precincts reporting. Businessman Tom Knox had 28 percent, followed by U.S. Reps. Bob Brady and Chaka Fattah.
Nutter surged in the final weeks of the campaign after spending months attacking two-term incumbent John Street, who is barred by term limits from running again.
The Democratic primary winner will be the overwhelming favorite in November. Nearly four of five city voters are Democrats and the city has not elected a Republican mayor in nearly 60 years. Business leader Al Taubenberger was unopposed in the Republican primary.
