I know we've gone around about this before... But I am loathe to attack state sovereignty... The precedent you seek could offer fertile means for liberal states to gang up and coerce individual states with any number of grievances.
In that, I think sovereignty remaining sacrosanct is far more important than any immediate gain.
I, too, am loathe to attack State Sovereignty. However, the Constitution all States chose to go by, either at its adoption or gaining statehood says that the Legislatures of the Several States shall make election law. In many States that very election law was altered by persons other than the legislature. In that sense, the Compact was violated, the rules for making the rules were not the same as they should be (up to the various State Legislatures, not appointees or other elected officials).
There is a difference. The Constitution was violated, incidentally, most often in the states that stopped counting, saw a mathematically impossible increase in Biden votes, and which carried the day in the electoral college for Biden, in each having him come from behind after counting was re-started. Other mechanisms of fraud have since been exposed, in those same states, made possible by unconstitutional rule changes regarding elections.
As we all have to suffer the effects of this election, we all have standing, and every state which cried foul should have had standing as well.
