CityLab Daily: Who Mayors Are Endorsing for President

First pick: Over the last month, mayors of some of the largest cities in the U.S. have registered their endorsements for the Democratic presidential primary. And many of the leaders of the nation's most populous and progressive cities are pulling the lever for the more centrist and moderate candidates of the current lot. Mike Bloomberg, the former mayor of New York, has earned the support of eight big-city mayors, including San Francisco Mayor London Breed and Washington, D.C., Mayor Muriel Bowser—to the disappointment of some of those cities’ more left-wing constituents. He's currently outpacing mayoral endorsements for frontrunner and former Vice President Joe Biden, while the other top-tier candidates—Senators Elizabeth Warren and Bernie Sanders—have only two major mayoral endorsements between them.
