The field for this year's at-large Boston City Council election continues to grow with a wealth of viable candidates. Mattapan's David Halbert is one of those candidates. While Halbert doesn't live in JP, he does have a strong connection to the neighborhood, having been the Jamaica Plain liaison for former District 6 City Councilor John Tobin. Halbert also previously worked for At-Large Boston City Councilor Sam Yoon, as well as Governor Deval Patrick. Currently, Halbert is the deputy director of community affairs at the Middlesex County Sheriff's office.
