“But who in the state? The governor? The State Legislature? A committee of that legislature? That’s the key. Let the GOP get control of enough governorships and/or legislatures and it should be a breeze, right?.................... “
That duty would generally fall to the state legislatures. If it was done in committee, they would still need a full floor vote.
I would rather not call a constitutional convention because it opens the door to political skulduggery by those who would like to destroy our country. And with the weak kneed-ed Republicans afraid of their shadow it could turn into a disaster.
