Actually, it is NOT special. These four states remain relevant because of a provision which says the new system will only take effect when states having a total of 270 electoral votes have signed up to it. Until then, those states will continue to cast their electoral votes based on the current system.
I don't find it at all surprising that four states would agree to this idea. You're always going to find at least a handful of states that will adopt practically anything, no matter how foolish. I'll be more worried when the number of states passing legislation in support climbs to a dozen (with 150 electoral votes).
Darn, I should have read the fine print. I was looking forward to these blue states making themselves irrelevent.
I guess the libs only believe in unilateral disarmament when it comes to America’s military. :-(
