Sure! The state of polygamy rights is way behind same sex but on the same path, there's no denying it. And there's no denying legalizing same sex marriage benefits poly rights.
This is good! Full marriage equality for everyone someday for sure!
See. Not that hard.
But seriously, most polygamists seem to be straight deeply religious folks, so I think that the fact that straight couples can marry with impunity right now is the biggest boost to the legality of marrying multiples.
You don't hear many gay folks wanting to marry many at a time. Seems to be a religious fundamentalist heterosexual thing.
