I suspect there are limits on how a state might allocate its EVs. Could a state allocate its EVs
It's not impossible if you read my post. Suppose IL wanted to award its EVs to the winner of the MO presidential vote. Would that be constitutional? It's not clear to me that SCOTUS would permit that since it is an assignment of IL electors unrelated to the vote taken in IL. It's certainly the case that the IL winner may not be the MO winner.
I think this be a violation of the 14th Amendment. There is not a right to a popular vote for presidential electors, but once a State decides to hold a popular election for presidential electors it becomes subject to the 14th Amendment.
Does at-large election of presidential electors violate both the 14th Amendment and the VRA?
