I think this verifies what I was feeling when the Windsor and related cases were handed down by the SCOTUS last year. Kennedy did not throw out state bans on gay marriage but his logic and wording, pointed out by Scalia, was an open invitation for Federal Courts to throw out the state laws/amendments. We all know where this is going to end with a 5-4 decision upholding these various Federal Court rulings declaring state bans unconstitutional. Over/under on years to legalization of polygamy?
I think polygamy is a different scenario, since it doesn’t have a huge fan base on the left like sodomy and lesbianism do. It is a feature of certain patriarchal cultural lifestyles that don’t have nearly the leverage this does. But I look for mandatory same-sex weddings in all 50 states and DC by the end of 2015 or sooner.
They should fight this on 10th Amendment grounds as well, such that Federal Courts CANNOT throw out whole Constitutional Amendments to the various State Constitutions.
