The NYT is reporting:

Mr. Bloomberg told reporters that he believed the Senate should hold an up-or-down vote on same-sex marriage, a position that seemed to conflict with that of Mr. Cuomo, who has said he will not introduce legislation to allow gay couples to wed until he is sure it has enough votes to pass.

In response to Mayor Bloomberg's promise to fund any GOP candidate who (ignoring his constituents) votes for SSM, NOM's Maggie Gallagher said this in the Times:

“The Republican base is incredibly united on this issue ... It’s a really bad idea to be for gay marriage if you’re a Republican, and I don’t think Mayor Bloomberg’s money is going to change that.”
