Well, to dip a toe in the waters of 'that horse has left the barn' I'll just point out that Trump, by several accounts, is not taking the daily National Security briefing , and that there has been little to zero communication with State on matters like communicating with leaders of other countries. If you are sticking with "nothing that I regard as significant or noteworthy has occurred during the transition period to date" then I must suggest that you either a) don't really give a crap about this stuff, or b) that you have not been paying attention-respectfully submitted. I cannot understand how the two items I have noted, not to mention a hundred other moments, are anything but significant and noteworthy.
