Senate Democrats said no thanks to Sen. Simcha Felder and now Senate Republicans are shutting him out of committee and leadership posts.

Senate Minority Leader John Flanagan on Thursday announced the Republican conference’s leadership and ranking committee roster with Felder absent from the list.

The Brooklyn Democrat, who kept the Senate Republicans in power by sitting on their side of the aisle, even lost his post on the Senate’s subcommittee on New York City education issues. The panel was created by the Senate Republicans for Felder to chair, but Staten Island Sen. Andrew Lanza will serve as its ranking member.

Senate Democrats earlier this week rejected Felder’s bid to join their conference after the party. Democrats hold 39 seats in the 63-member chamber.

Felder last year rejected calls for him to join the Democratic fold after the Independent Democratic Conference disbanded and rejoined the mainline conference.
