So far, the contenders are Dan Rizzo (a Revere city councillor), Tim Toomey (a Cambridge rep and city councillor), and Anthony Petruccelli (an East Boston rep, and apparently the insider favorite with backing from both Trav and Menino). Others, including the Winthrop harbormaster (!), are considering jumping in.
Needless to say, this is an important race. Seems to me that it behooves the progressive crowd to pick a horse in relatively short order. So, take the poll!
