This poll also did generic congressional ballot, and they found some
strong differences:
CT-2: 44D-42R
CT-4: 48D-38R
CT-5: 46R-42D
Democratic incumbents are outrunning generic Democrats consistently (or, if you like, Republican challengers are running behind generic Republicans). To some extent, this is a good sanity check; it's what you would expect to see if the generic congressional ballot and the Senate polls were coming from the same universe. But it's probably a good sign for Republicans -- it means that on balance mathematically more undecideds prefer Republicans to Democrats in the abstract.
Using 2021 patterns (straight swing from Biden vs. Trump), this poll gets you an expected GCB, per district, of R+6 in CT-2, R+17 in CT-4, and R+11 in CT-5. (On the other hand, once you name the actual candidates, this swings to...D+16 in CT-2, R+11 in CT-4, and R+7 in CT-5).
So on the whole probably quite a strong poll for the GOP.
