They're getting desperate.
Kentucky state Representative Joseph M. Fischer (R) has introduced a bill to essentially bypass the Supreme Court's ruling against gay marriage bans by renaming marriage to "matrimony."
Fischer has introduced HB 572, the “Matrimonial Freedom Act” — an epic 454-page bill that creates the new status of “matrimony.” Declaring that the Supreme Court has established an “absolute Tyranny over these States,” the bill asserts, “we have full power to define marriage and to establish a new institution of matrimony in this Commonwealth,” adding, “with a firm reliance on the protection of divine Providence, we mutually pledge to each other our Lives, our Fortunes, and our sacred Honor.”
Naturally, Fishcer's institution of "matrimony" would only accommodate straight couples.
Fischer's bill, HB 572, is apparently over 450 pages long because renaming and redefining the institution of marriage requires renaming it across all applicable state laws and codes that apply to marriage. Representative Fischer also filed another bill, HB 571, that amends the state Constitution to replace marriage with "matrimony."
Granted I am not a constitutional law professor or even a legal clerk, but I'm fairly certain you cannot circumvent the Supreme Court's ruling by simply renaming marriage and establishing a new set of rules for it.
I don't expect the legislature will pass Fischer's bills but even if they did the very first federal judge to get a whiff of it would laugh it out of the courtroom.
