Only potentially exportable.
There are 40 states holding the line on traditional marriage. I don't think that will change a whole lot.
True, but as far as federal law would be concerned, these couples will be able to file joint federal tax returns, receive survivor social security benefits, and other federally overseen programs administered by states, such as Medicare, wherever they choose to live. Federal governments operations is so inextricably woven into so many state programs (unfortunately) that it will be nearly impossible for marriage-honoring states to avoid conflicts with these concocted relationships. And with a federal government hostile to natural marriage as the real thing, you know they will extort compliance with their perverted wished from these states.
