Texas will refuse to accept that insanity.
On what constitutional grounds are they doing this?
Texas doesn’t have to accept it. But Texas might gain by it. Right now Presidential candidates ignore Texas because its vote is a foregone conclusion.
The Constitutional grounds are that each state is free to appoint their Electors any way they see fit.
Ohio could have a convention of PTA Presidents choose its Electors and there’d be nothing to say about it.
