That’s a plausible argument.
It is not true, however, as some are arguing that they cannot do this because the election for President in a state is a “Federal” election - it is not - it is a local election created by acts of the legislatures of the several states.
This means any minority that is prohibited from voting for a constitutionally eligible presidential candidate under one of these stupid laws has all the legal standing he or she needs to have the law overturned.
Heck the Voting Rights Act gives very broad powers to the DOJ to enforce this.
