Not only that, but Trump's call for a national emergency will be in District Court in the blinking of an eye, relatively speaking. Immediately following his official declaration, an injunction will be sought and granted. The case will wend its way through the circuit court and land at the Supreme Court, all at light speed. After oral arguments, it won't take the Court long to draft its unanimous, 9-0, opinion. Political disagreements must be resolved via the legislative process. They may not be resolved by declaration of an emergency, particularly without any emergency having been demonstrated. Left with out options, Trump will propound another lie-excuse, and the government will be up and operating. We are likely looking at two weeks at the most.
Importantly, this "Wall" fiasco will mark the beginning of the end of our true national emergency. Trump and his ragtag administration, by now down to rejects, will emerge totally and irreparably emasculated. Whether Trump is left where he is, for political reasons, or removed, will depend on both parties, not just republicans. And in any case nothing will be done until after the Mueller Report.
As soon as the Mueller report is out , and the lying, blaming, and gnashing of teeth subsides, things will move quickly back to normal. The absurd tariff-wall-caravan-terrorist nonsense will be over. Market volatility will move to normal, and life on main street will return to "Honey I'm Home, What's for dinner."
We'll have had our little fling with, "best way to fix somth'n not entirely broke, y'all, is to burn it down, I reckon." It's been instructive in that we learned we don't want to do that again. And we will have used a time honored method to get rid of any fool. Just give them enough rope, be patient, and they'll hang themselves!
There can be only one true question remaining to be answered, and that is, "Does Sarah Huckabee Sanders's history include a lobotomy that her family has tried to covered up?" -- if so, the cover-up has not been entirely successful.
