This was detailed in the recent "Cheese in the Maze" article. In short, while the media perseverate over the tweet, WINNING happens elsewhere. Here's a back-test of that theory.
Friday, July 28 - Trump tweets "I am pleased to inform you that I have just named General/Secretary John F Kelly as White House Chief of Staff. He is a Great American...." and "I would like to thank Reince Priebus for his service and dedication to his country. We accomplished a lot together and I am proud of him!"
Everyone spends the weekend losing their mind.
On Saturday, July 29, Trump tweets about eliminating the filibuster.
July 31 - Kelly is sworn in as COS. Trump tweets "A great day at the White House!"
August 1 - count 'em, one, two, three tweets...none about judges.
Which is "odd"...BECAUSE...the Senate on August 1 confirmed Kevin Newsom to the 11th Circuit, joining Sixth Circuit Judges Amul R. Thapar and John K. Bush as confirmed Trump appointees. Ralph Erickson has already had his hearing and should be confirmed soon for the Eighth Circuit.
Thus, I'd recommend popcorn when looking at tweets while preparing for something bigly to happen.
