The movie is predicated on a ridiculous suppostion: CA and TX are mortal ememies and would NEVER join forces.
Perhaps that was the point
I agree that Abbott’s Texas and Newsome’s California are not on the same side now.
But I think the plot device of making California and Texas the two states in the movie’s Western Forces is what makes it hard to definitively equate either the Trump or Biden side of politics now with the movie’s authoritarian federal government.
