I am honestly more concerned the GOP could gain so much control over state legislatures that they could eventually convene a Constitutional Convention, where they rewrite the 1st Amendment to state that the US is a Christian nation or something like that.
This could lead to a supermajority control of at least 30 state legislatures. They’d need 34 to meet the requirements for a Constitutional Convention
Amendments proposed during a Constitutional Convention must also be ratified by three-fourths of the states.
