In NYC, a crowded mayoral race to save a city 'gone to hell'

Primary voting is underway for the next mayor of New York City. The winner will be tasked with a long list of challenges: reviving the city's economy, curbing rising rates of violent crime and police reform. Filling the needs of more than 8 million people in America's largest city is not an easy job, but it hasn't stopped more than a dozen Democrats from running for it. Hari Sreenivasan reports.
