I ain’t holding my breath. I’ll be shocked if they uphold the bans and let the states decide.
I don't think it will be an either/or case; the Supreme Solomons will "split the baby," at the cost of the baby. And the false mother will not object.
They're likely to let states continue to define the requirements for getting married, but require them to honor these redefined "marriages" from other states.
Or, they'll craft together a requirement for all states to offer "marriage"-like civil unions to sodomites, effectively gutting the institution just the same.
