The fact that every one of the eleven jurisdictions (ten states plus the District of Columbia) is a deep "blue" state in presidential elections should have been the first clue to the author of this garbage that this idea is idiotic.
The compact isn't even legally binding. In a presidential election year, any state that signs it can simply drop out of it between Election Day and the Electoral College vote through a vote of their own state legislature.
I thought the states were forbidden to enter such compacts.
