We know what happens when a State or States

secede from the Federal Union, we found out in 1861, Civil War Breaks Out.  But what happens when the Federal Government decides, whimsically, to go to war with an individual state on purely partisan grounds?
Because we seem to have reached that point in Michigan, where the White House is seemingly pressuring vendors not to sell PPE to said state because the incumbent regime has a grudge against the Governor.
My recommendation to Governor Whitmer is to outreach to Canadian vendors and see if anything can be procured there.  I'm thinking Canada simply to exploit a short supply line, but other foreign sources should be cultivated if possible. Likely there is nothing much to be found, but it's worth a try anyway.
This "policy" from the White House is politicizing mass murder quite frankly, but it is almost beside the point. The constitutional issue remains what is the corrective when the executive department goes berserk and starts randomly settling scores with individual states?
Per a strict reading of "The Federalist Papers", it was assumed by the founders in the unlikely situation described above that the coequal branches of the US Government would step in to redress the situation.
Well we saw how well that went back in January with the so-called "Senate Trial", the Courts as well, packed as they are with vengeful witch burners seem equally hapless in this crisis.
There is also the 25th Amendment, but that depends on the VP being a better man and better patriot that the groveling toady that is Mike Pence.  Or another Senate Trial...likely an impossibility given the current pathogenic situation, to say nothing of the politics of the idea.
After that whats left?
Mass Civil Disobedience? We aren't yet outside the US Constitution based on the notion of "petitioning for the redress of grievances, but we are getting there all the same.  I don't know what must happen next, I think wise action starts with a self admission that critical leadership personalities have deliberately failed us, and they must be compelled to leave public office, now.  Rights are inalienable no matter what the circumstances, the right to compel a change in leadership most of all.
