You have 2 choices, Peter King, or a Long Island Democrat that is further to the left than Anthony Wiener. Heck the left right dichotomy doesn’t work, it’s either King or a union backed self-declared socialist.
Long Island (NY-3) will never again be a Republican district. Ever. Not even after the Second Civil War, the state of New York declaring bankruptcy, or an Iranian nuclear attack on NYC. King is the rear guard action, do not throw him to the wolves until King has breathed his last breath of resistance.
There’s lots of choices. Limited only by your imagination.
