To which court would he take it? SCOTUS has already told us that states cannot seek to enforce the constitution there.
Democrats are somehow able to find some district court judge somewhere to issue an injunction that nullifies California state constitution, Kentucky religious protections, Louisiana abortion laws, or federal immigration laws. I'm sure the GOP could find a judge somewhere willing to do the same.
This new law makes it illegal for the State of Georgia to lower state taxes. Congress simply does not have this power under Article I. It also violates Article IV, Sec 4 as well as Amendment X. Yet not one Republican legislator has called them out on it.
