how all of those states are going to be willing to vote against their self interest.
Vast majority of the states (and electoral count) that have 'joined' are solidly blue. Red states, for fairly obvious reasons, are not nearly so interested. And, as we have seen in the past - the concept of 'fairness' as embodied in state legislators - tends to run strongly in the direction of party. Please explain how people that are busy in efforts to disenfranchise voters in their own state - suddenly become interested in enfranchising a population (and outcome) weighted toward other states and demographics?
