News reports described the city council's Progressive Caucus as the real winner of the 2013 elections. Prior to the election, the caucus had 11 members. Ten of those 11 members were re-elected to the council by voters, along with six caucus-endorsed candidates and four other new members known for views aligning themselves with the caucus.
