I'll look that up for you. Your U.S. representative for Massachusetts's 9th congressional district (MA-09) is **Bill Keating**, a Democrat. Massachusetts' 9th Congressional District in the United States House of Representatives is represented by Bill Keating (D). He has served as Representative for Massachusetts's 9th congressional district since Jan. 3, 2013. For reference, the district is located in eastern Massachusetts. With a Cook Partisan Voting Index rating of D+6, it is the least Democratic district in Massachusetts, a state with an all-Democratic congressional delegation. Redistricting after the 2010 census eliminated Massachusetts's 10th congressional district; the 9th covers much of the old 10th's eastern portion. You can reach his office through his official website at keating.house.gov.
