I watched this earlier & like Dr. Janda's theory. Video about 10 mins.
TL;DW: 35 day shutdown was like a business soft opening to see where the bugs are. Marketing of border issues delivered to public hard and often by Trump, which is his strength. Now all know the issues and why it will only work if there's a wall. Dems offered no tangible alternatives. OPM set up RIF stopwatch , with streamlining suggestions and performance ratings having been done by end of 2017. AWOL warning & policy put in place. Biggest issue was TSA, but some airports have private contractors who can fire workers at will. SF int has private security services working under TSA rules. No problems,
Dr. Janda's guess is hard shutdown goes live on 2/15. Thinks constitution upholds pres powers to do so.
