Map: Where Challengers Forced Runoff In District Attorney Race

Challengers George Gascón and Rachel Rossi combined to nab more than 50% of the vote in the race for Los Angeles County District Attorney. That denied incumbent D.A. Jackie Lacey the majority she needed to secure a third term, and sets up a rematch between Lacey and former San Francisco D.A. Gascón in November.

With the election results certified, we've mapped the results at the precinct level. Green areas saw a majority for Lacey. Pink ones mean her challengers combined for more than 50%.

Lacey found strong support in pockets all across the county -- particularly in the Antelope Valley and Santa Clarita. She also won majorities in San Dimas and Rolling Hills Estates, and did well in Lakewood, Torrance, and the Northwest San Fernando Valley.

But in other parts of the county, Lacey failed to secure even a third of the votes, including West Hollywood and Culver City.

She struggled in broad swaths of the city of Los Angeles, and netted less than 40% in areas as diverse as East Los Angeles, South Gate, Santa Monica, and Glendale.

Nevertheless, Lacey won 48.7% of votes countywide. Neither Gascón nor Rossi won a precinct outright where more than 10 ballots were cast.

Lacey, a two-term incumbent, touts herself as a "reasonable reformer." But she has come under fire from criminal justice reform groups. "She's not standing up for the people of the county when police are the perpetrators of the crime," Black Lives Matter co-founder Melina Abdullah told LAist.

Gascón and Rossi both ran as reformers, promising to end cash bail, reduce jail populations, and address stark racial disparities in the criminal justice system. The challengers both promised action following a KPCC/LAist investigation into mega-landlords Mike Nijjar and PAMA Management.

The District Attorney's race was thrown into turmoil the day before the election, when Lacey's husband pulled a gun on protesters in front of the couple's home. By that point thousands of voters had already cast a ballot.

Gascón received the second-most votes in the March election, netting 28.2% of the vote. He and Lacey will face off on the November ballot, with the winner leading the nation's largest local prosecutorial office.
