If Texas had no standing in the process of the States following the rules to select the President at the SC (one of it's specific duties IS disputes between the various States) then no State or branch of the Federal Government has any standing to prevent the State of Texas from leaving the union in which they have zero representation.
We are not "subjects" of the Federal Government and if the other states are allowed to violate their own codified laws by the Federal Government, then the the laws of that government are meaningless to The State of Texas.

I agree as that is my ultimate point. Those genius/treasonous political activists on the SC just told Texas voters that they will never get representation in their court. If they won’t take a case that involves their (Texas’) representation for their (or any states) commander-in-chief, all other precedents are effectively rendered moot or of lower standing.
