Seth Barron talks with four City Journal contributors—Rafael Mangual, Eric Kober, Ray Domanico, and Steven Malanga—about former New York City mayor and now presidential hopeful Michael Bloomberg's record on crime, education, economic development, and more.

Bloomberg's record on crime will factor heavily in his campaign, but his 12 years as mayor were eventful in numerous other policy areas.
