Open seat -- the current officeholder is a Republican, Elise Stefanik, who is not running (retiring from public office).
Why we think this
- This district's baseline partisan lean favors Republicans by about 10 points of margin before anything else is considered.
- This is an open seat: the current officeholder (a Republican, Elise Stefanik) is not on the ballot, which tends to make the race more competitive than a defended seat.
