It doesn't exist.
Kings County has the highest enrollment of registered Democratic voters in the nation, albeit an insipid participation rate in Dem. primaries, and for good reason.
The only Republican club that I know-two of them used to exist in my neighborhood, before legal trouble forced them to shutter their doors-is in Bay Ridge.
I used to be a member before it dawned on me that the age of the average member was pre-deceased.
There actually is a Young Republican club here-I know one or two members-but I've never really investigated it.
Occasionally I'll get a mailing or two advertising some meeting they're holding, usually at Peggy O'Neill's, a local bar.
OPINION: Well, that's really sad. It seems like your area is ripe for a change.
