Who Represents Plymouth
Plymouth is big enough to be split between two state House districts, so the representative for your street depends on your precinct. One state senator covers the town, in a district that reaches across to Cape Cod. In Washington, all of Plymouth is represented by one member of Congress and the Commonwealth’s two U.S. senators.

What this seat decides
The state and federal seats
Your State Representative and your State Senator. State law: the driving age, the minimum wage, the bottle deposit, and Chapter 70, the formula that decides how much state money your schools get. They also carry a home rule petition to the State House when your town votes for something state law does not yet allow it to do.
Your member of Congress and your two US Senators. Federal law and federal money, and help with a federal agency like Social Security, the VA, or immigration when someone in your family needs it. They also nominate candidates to the US service academies.
