A "blue wave" has not been seen in Long Island Election Day races, as some incumbents in the U.S. House of Representatives and state Senate hang in the balance on Long Island.

Among the tightest races is for the 3rd Congressional District, pitting Rep. Tom Suozzi against political newcomer George Santos. Suozzi trails by just a couple of points at this point, but absentee ballots have not been factored in and won't be until next week.

Suozzi says he feels good about where the remainder of the votes will go, but Santos is feeling the same way.

"I'm just saying that on election night, it seemed like a very good red wave. And historically absentee and mail-in ballots tend to go the same way that election day voters vote," claimed Santos.

Larry Levy, of the National Center for Suburban Studies at Hofstra University, says Tuesday was a good night for Republicans on Long Island, and that things were amplified due to "unrealistic or unrealized expectations for Democrats."

Elsewhere, some other Democrats are claiming victories or holding sizable leads at this point. Those that could be unseated include Sens. Jim Gaughran, Monica Martinez, and Kevin Thomas, who are currently trailing in their races.

In District 3, Sen. Monica Martinez is losing to Republican Alexis Weik of Sayville. Weik is the former Islip town receiver of taxes.

In state Senate District 5, Huntington Councilman Republican Edmund Smyth leads incumbent Democrat Jim Gaughran from Northport.

The District 6 seat could go red, with Dennis Dunne leading Democrat Kevin Thomas.

The retirements of state Sens. Kevin LaValle and John Flangan left two seats up for grabs - both favor Republicans at this point.

And if in the end those seats do flip to Republicans, will it lessen the voting power for Democrats on Long Island? The state Senate and Assembly both had a large Democrat advantage coming into election night.

"It depends on how both parties decide to play this -- will they create a Long Island block that includes Republicans and Democrats? Will they reach out to suburban moderates around the state and create a suburban block? It remains to be seen and it's in the interest of both parties to do something like that," says Levy.
