Levy in CT is a true long-shot.
The last Republican US Senator from CT was Lowell Weicker (1971-1989)—and he was to the left of most of the Democratic Party at that time.
There have been no truly conservative Republican US Senators from CT in modern history.
The other one to keep a bit of an eye on — longer shot then O’Dea or even Levy, but not impossible if the wave is big enough:
My political consultant friend whom I cited above says if Zeldin wins, Michael Henry wins for NYAG, and if Zeldin wins by more than 4, he likely carries Joe Pinion in with him. (Pinion is Schumer’s opponent.)
(If that happens, they need to find a candidate named Rack so teh two senators can be Rack and Pinion.)
