The New York Conservative Party generally has its greatest support outside of New York city, yet for the last three elections, its strongest district by far has been in Brooklyn. Starting in 2018, Assemblymember Simcha Eichenstein has been elected in the Borough Park neighborhood as the nominee of the Democratic and Conservative Parties. Republicans have never nominated a candidate in his race, which was in the 48th district in both the old and new redistricting.

The Conservative Party share of the vote in 2018 was 38.59%; in 2020 it was 51.62%; and in 2022 it was 44.57%. Even though Eichenstein is a Democrat, many of his constituents prefer to vote for him on the Conservative line, so much so that in 2022, the Conservative Party polled more votes than the Democratic Party. Eichenstein is a voice for Orthodox Jews.
