Considering that, statistically speaking, no one wants homo marriage in the U.S., maybe the constitutional republic will be done a favor if Kennedy does as expected. Maybe in a core of states, the legislature and governor will pass a resolution citing the exclusive authority of the States over marriage, and instructing the state attorney general to ignore the USSC's ruling on this matter.
The following morning, the sun will rise on schedule.
This is a collision that needs to occur, since USSC over-reach began in earnest in the mid-20th century with the fanciful "incorporation doctrine"—a doctrine specifically outlawed in advance by Article 10. Perhaps the "streamlining" of USSC fiats should begin here, now.
Sorry! I meant to say, "by the 10th Amendment."
