Two items on this front today from PoliticoMA:
Setti Warren, fresh off an announcement that he will not seek re-election as Newton’s Mayor has hired former MDP Chair John Walsh as a consultant. Other names are mentioned at the end of the article.
Also, there is a link to a Globe article about an effort to draft John Kerry, who did serve as Lt. Governor 30+ years ago.
Candidates may start appearing as early as the 2017 caucuses, though that didn’t seem to help Joe Avellone.
