Let's also disabuse ourselves of the notion that Tiny is doing the shutdown as a distraction from the Mueller investigation. He's only getting more unpopular the longer this drags on. Once Mueller's report hits, Tiny's popularity starts to matter.
But it's possible that he is doing the shutdown as a distraction from lifting sanctions on Oleg Deripaska. For some strange reason, the Trump administration is trying to lift sanctions on this Russian oligarch. The administration is required to give congress 30 days to object and they started the clock just before Christmas.
So it's entirely possible that this shutdown is a smokescreen designed to let Putin's Puppet do Russia's bidding. Judging by the fact that nobody on this thread has even mentioned it, the smokescreen seems to be working.
