If only and all states with R governors pass this, it will hurt us; it needs to either be be just blue states with red state leadership (feasible) or all states (not feasible).
Yes, I have to agree with your point, and I realized that.
Ideally, it would work best if all states changed the apportionment of electoral votes, but that is not going to happen.
On the other hand, republicans are currently in control of what are usually regarded as blue states such as Pennsylvania. We got Ohio too. And we have Virginia. And Florida. The advantage is obvious.
It is quite possible that states will go back and forth on how they allocate the electoral votes depending on the party in power. If we have control of a blue state why not go for it? We have to take every advantage we can get against the cheaters.
The odds of us periodically controlling a blue state are infinitely better than a red state going blue.
