Mayor Bill de Blasio is getting a challenge from the left; police reform activist Bob Gangi is jumping into the mayor's race. But his entry may do little to shake up the sleepy race, in which de Blasio has the upper hand. NY1 political report Grace Rauh has the story.

Democrat and police reformer Bob Gangi is entering the mayor's race with an agenda that directly questions Mayor de Blasio's progressive bona-fides.

At the top of his list? A call to end broken-windows policing, in which police officers crack down on low-level offenses, like turnstile jumping.

"These practices are blatantly racist, deeply inhumane, and they should stop," Gangi said.

Gangi says he will fight for smaller class sizes in schools and free tuition for CUNY students from low- and middle-income families.

"De Blasio has failed to follow through on his progressive agenda," Gangi said.

But it is not just the mayor's lefty credentials that Gangi is attacking.

"I was born and raised here. I've always lived here," Gangi said. "I eat pizza with my hands. I root for home teams."

De Blasio grew up in Cambridge, Massachusetts, and is a Red Sox fan.

But while Gangi's policy plans may be more fleshed-out than other mayoral hopefuls, he is a long-shot candidate at best.

"We're going to take a page out of Beyonce's book, and we're going take a lemon and make it lemonade," Gangi said.

His kick-off outside police headquarters had a homespun quality. "I only want softball questions," he said. "Indicate if it's a softball."

At one point, a song playing on his own phone interrupted his event. "Sorry. That's music. Just kill it," he said to one of his staff members.

A spokesman for the mayor's campaign said: "Mayor de Blasio expanded pre-k for every 4-year-old and raised wages for tens of thousands of workers. Crime is at record lows, jobs are at a record high, and New York City is building affordable housing at a record pace. That is the Mayor's record, and one that New Yorkers are rallying around."

The mayoral field may be getting more crowded, but so far no one has emerged as a serious threat to de Blasio.
