Well, it was only a matter of time, wasn't it? It was the logical next step for them to take, and the only way in which to ensure that they get what they want. After all, a Supreme Court that actually interpreted marriage laws in light of the Constitution -- which, after all, says not one single word about marriage of any sort to anyone -- would be forced to state that all the various DOMA laws would automatically fall should any one state recognize gay marriage (and that, moreover, full faith and credit would require all states immediately to recognize and accept Vermont's civil unions as though they had taken place in their own states).
And, of course, if Congress does pass this amendment -- and if it's submitted to the floor, it will almost certainly receive the supermajorities required for passage -- the states will seize it joyfully and pass it before anyone can even blink.
