I honestly don't think this is about Trump anymore. If anything I get the very distinct impression the Attorneys General of these states would rather Trump and his "Team" go sit in the corner for the time being. There is a deeper game afoot here, and this one has deep roots in American History. Trump was simply the bull in the china shop that ripped off the band aid. For over a century there has been a steady erosion of State power in favor of ever more massive, ever more overbearing national government. One whose roots lie in the Civil War, but only truly began to flower in the last 50 years of the post world war 2 era. This lawsuit by Texas and its growing coalition is essentially the shot across the bow.
This "lawsuit" (its not a lawsuit) is essentially a declaration that in the mind of these States, other States of the Union have decided the Constitution that binds the country together no longer applies. However, since THEY think it still does, they are asserting their rights. And they are demanding their rights as Sovereigns to have their grievance heard by the Court. Capital "C" Court. An overlooked part of the Texas petition is that they not only argue the Supreme Court is the proper venue, they argue that the Supreme Court MUST hear their grievance. That is has no choice in the matter. If the Supreme Court rejects this notion, it is making a precedent in its simple silence. In that the States cannot hold sovereign grievances of political nature with other States.
More perversely, it would acknowledge that if a State holds a Political grievance with another, then it has no peaceful or legal remedy to address that grievance. Which leaves non peaceful and illegal methods as the only available recourse to address the grievance. An old wound is getting ripped open here, and I am sure
@ConfederateIrishman will give me another late sticker as if I am just now realizing shit like this, but this has been a clash a very long time coming. Trump was merely an accelerating agent.
