Repealing marriage equality in New Hampshire?

Same sex marriage in New Hampshire is legal, under action of the legislature. But thanks to the 2010 Republican victory, that could be shortlived.From user jpmasser at Daily Kos:

Already four Legislative Service Requests (precursors to formal bills) with intent to redefine marriage solely between a man and a women have been filed by members of the new legislature. It seems all but certain that one such bill will be brought up and passed in the coming session, vetoed by Democratic Governor John Lynch, and then a veto override attempted.

What will it take to sustain the Governor's veto? Assuming all remaining Democrats would vote to sustain the veto, it would take four Republican Senators, for a total of 9 votes of out 24, or 32 Republican House members, for a total of 134 votes of out 400 to deny a two-thirds supermajority. My understanding is that the former (finding four Republican Senators) is considered extremely unlikely, leaving it to defenders of marriage equality to round up at least 32 House Republicans (and possibly more, if there are Democratic defectors) -- approximately 11% or one in every nine Republican House members.....

[A]re national LGBT organizations up to fighting these bills-to-be before they become law in any sort of serious way? So far I've seen little to suggest that national organizations like the Human Rights Campaign or the Courage Campaign are focusing effort on New Hampshire. Did they fail to learn the lessons of California in 2008, and then again, of Iowa in 2010 where the battle was never even joined?

From notes on their web site, the New Hampshire Freedom to Marry group seems to be organizing, but I suspect they will be outgunned, outspent and outpeopled by NOM and other hate groups unless there is aid and assistance from national groups.

Opponents of equality will stop at nothing to gain the victory they so desire: a rollback of human rights in New Hampshire. It's time for the LGBT Community and supporters to wake up from the pleasant dream that was the vote on Don't Ask, Don't Tell's still-to-be-realized repeal and smell the stench that is about to rise in New Hampshire. However badly I mix metaphors.

It ain't over even when we think we win.
