But on a realistic note:
The likelihood of law suits blocking Trump's emergency
is probably 100%.
There will be a lot of plaintiffs... probably ranging from Corporations (both for profit and non-profits) to the Democrats to various groups and individual citizens to individual states.
It all depends on which and how many government programs are impacted and which civilian entities are impacted... etc.
It is likely that most if not all of these suites will out last Trump's term of office, especially if the various plaintiff spread out their law suites over 12 to 18 months in various parts of the country.
If Trump is not re-elected, the next president will most likely drop the case.
In spite of what McConnell says, Congress could block the redirecting of allocated funds...they probably will have to do this with some programs.
Even if Trump is re-elected, it won't be a done deal.
What "it" will really do is divide Americans more.
In addition, our economy is presently vulnerable... this could easily tip the proverbial scale.
Regardless of all that
we can be certain of one thing: Putin is probably very happy.
