The first state to do so the old-fashioned way, i.e. legislatively, instead of by court ruling. It was close in the house but they got it done:

The Legislature voted Tuesday to override Gov. Jim Douglas’ veto of a bill allowing gays and lesbians to marry. The vote was 23-5 to override in the state Senate and 100-49 to override in the House. Under Vermont law, two-thirds of each chamber had to vote for override.

The vote came nine years after Vermont adopted its first-in-the-nation civil unions law.

It’s now the fourth state to permit same-sex marriage. Massachusetts, Connecticut and Iowa are the others…

Craig Bensen, a gay marriage opponent who had lobbied unsuccessfully for a nonbinding referendum on the question, said he was disappointed but believed gay marriage opponents were outspent by supporters by a 20-1 margin.

Normally this is where I’d gauge whether a constitutional amendment to overturn the decision is feasible or not, but since Vermont’s gone off-script I’m without an angle here. No reaction yet from prominent social cons either, although Huckabee, Romney, and Palin are all on record as supporting a Federal Marriage Amendment so it’s safe to assume they want this overturned even without the dastardly handiwork of “activist judges.” In lieu of further comment, let’s take the temperature of the Hot Air faithful with a poll. You’ve got three choices — the social con option, the federalist option, and the libertarian option. I’m curious to see how it’ll shake out. Why, even Rick Warren’s backing away from this fight.
