You are most likely correct. The caveat is if a majority of Texas started raising hell about it. If Abbot, et al, didn't listen, their political careers in Texas would be OVER. And they probably would not be safe to live in the Lone Star State. Texans have a long history of rebellion and distrust of government.

A plausible scenario of getting desired results from the US gov would be to terminate oil & gas exports to any blue states and/or US as a whole until election fraud was satisfactorily addressed.
