In a press release from their website they state,
First off, more power too them...waste your money in New York - a State which has no chance of repealing the marriage equality law. It comes with the added benefit of siphoning money away from Minnesota, which will be having a ballot referendum on marriage equality in 2012. Secondly, just so that these four brave Republicans know that the LGBT community does not take their support lightly, I urge all of us to contribute - whether it be financially or physically - to their reelection campaigns. As I said yesterday, these four brave men have stuck their necks out for us and have incurred the wrath of their base; they deserve our support.
The second paragraph really gets me though; for Senators such as Mark Grisanti of Erie/Niagara/Buffalo, addressed this issue of "betraying voters". I would all encourage you to watch his floor speech, for he shows the heart of a true statesman.
