Menino Vetoes Boston City Council's Redistricting Map: Boston Mayor Thomas Menino vetoed the redistricting map submitted by the Boston City Council, saying the map "concentrates our many citizens of color into too few districts, and in doing so may limit their equal opportunity to elect candidates of their choice." In his letter to the Boston City Council, which was received by City Council President Stephen Murphy today, Menino outlined his suggestions for improving the map. (The letter is attached to this article.) The Boston City Council contentiously approved the redistricting map, 7-6, on August 23. -David Ertischek
