MIT grad here. I have a theory for you autists. Maybe it's been said already, but here goes:
Q last posted on 10/9/2018. That day is exactly 28 days from election day. Q cannot post until the election so as not break election interference laws (Hatch Act etc.). Four weeks is a reasonable interval (maybe even statutory) so as not to "interfere" with the election.
I hope I am wrong, but hold tight. It will be glorious. You know Trump is saving some master moves until right before 11/6.
