Who is my U.S. representative in MA-09?

Captured 2026-07-10 21:18:13 UTC Model claude-opus-4-8
I don't have reliable, up-to-date information about who currently represents Massachusetts's 9th congressional district, and this is exactly the kind of fact that can change with elections.

**As of my last knowledge, MA-09 was represented by William "Bill" Keating (Democrat),** who has held the seat since 2013. His district covers areas including Cape Cod, the South Coast, and parts of southeastern Massachusetts.

However, I'd strongly recommend verifying this, since:
- Election results, resignations, or other changes may have occurred after my information cutoff
- I want to make sure you get accurate, current information

**To confirm your current representative, you can:**

1. **Visit the House of Representatives website** at [house.gov](https://www.house.gov) and use their "Find Your Representative" tool by entering your ZIP code

2. **Check the Massachusetts Secretary of State's website** for election and district information

3. **Look up your specific address**, since congressional district boundaries can sometimes place neighboring areas in different districts

Would you like help finding any other information about the district or how to contact your representative once you've confirmed who it is?
