Not one single governor of any state, red or blue, has used the police powers vested in him to prevent the enforcement of the Supreme Court decision. If the states refuse to interpose their authority against that of the Federal government, the "gay marriage" ruling will stay in place until the national government falls. Congress has never used its authority to restrict the appellate jurisdiction of the Federal courts. Amending the Constitution, either conventionally or through a Convention of the States, will not work because in either scenario, you would need to get three quarters, or 38, of the 50 states to ratify any amendment. I cannot imagine any Northeastern state, except maybe Pennsylvania, or any West Coast state, except Alaska, where an amendment overturning this decision would pass. That would be 14 likely "nos", even excluding Illinois or Minnesota.
The illegitimate dictate of the Supreme Court is of greatest concern. Such action can not be tolerated.
