Four Republican senators voted for the gay marriage bill last year: Jim Alessi, Mark Grisanti, Steve Saland and Roy McDonald.
And wealthy former Republican gubernatorial candidate Carl Paladino says he has lined up Republican challengers to primary three of them, challengers he would be expected to strongly support financially.
... In an interview at the Republican state convention in Rochester, Paladino said he has challengers lined up for Alessi, Grisanti and Saland — though the Buffalo millionaire declined to name those people at this point, saying the campaigns themselves would make the decisions about campaign announcements. The fourth senator, McDonald, appeared likely to faced a primary challenge from Assemblyman Steve McLaughlin, but the assemblyman recently decided to take a pass.
... For a whole host of reasons, Paladino is also very, very unhappy with Republican Senate Majority Leader Dean Skelos, and is actively trying to unseat him as Republican leader.
