Mark Sylvia's seat is marked. Seats run from most liberal (left) to most conservative (right), by contested floor votes. Color shows how often each member crosses party lines toward the middle on votes that divide the parties: solid blue or red means almost never, and purple means on at least 1 in 10 of those votes. Gray seats are members too new to score. How these numbers work

Budget projects

Massachusetts's budget acts don't name the legislator who asked for an item, so there's no budget figure for Massachusetts legislators.
