I’m telling ya ... Full Faith & Credit is coming. It’s 5-7 years away, but it’s coming.
I would not be surprised if it was sooner than that. Perhaps much sooner. Although the opinion in Windsor was nominally grounded in the states' ability to regulate marriage, the overall reasoning (if you want to call it that) of the decision could very easily be extended to either (a) require the states to give full faith & credit to same-sex "marriages" performed elsewhere, and/or (b) require that all states perform same-sex "marriages." I would guess that the case that will eventually wind up in front of the Supreme Court on one or both of these issues has already been filed in some Federal court somewhere.
