Read the constitution, something the democrats should do before they do idiotic things to try and fool people with their BS antics. No states, as of now, can actually award their EC votes to the popular vote winner.
However, the electors can choose to give their votes to which ever candidate they want but are usually pledged to give them to the candidate that wins the state. Now some states have a split EC vote, the votes are split according to vote tally. I think only two states do that now but in the past most of them did instead of the winner take all system most states use now.
So, don't worry business as usual as far as EC votes go.
Where does it say a 2/3'rds majority is needed? The constitution only mentions the "Consent of Congress".
Article 1.
Section 10...............
No State shall, without the Consent of Congress, lay any duty of Tonnage, keep Troops, or Ships of War in time of Peace, enter into any Agreement or Compact with another State, or with a foreign Power, or engage in War, unless actually invaded, or in such imminent Danger as will not admit of delay.
“No states, as of now, can actually award their EC votes to the popular vote winner.”
And that is a scheme designed to defeat the original intent of the framers, which was to provide a senate and electoral college that gave some additional weight to the smaller states (colonies).
And they certainly anticipated the situation where a candidate could win the popular vote, but lose in the electoral college. It’s what they intended, and anything that tried to defeat that would probably be ruled unconstitutional.
The states formed the union, and not the other way around. And those compromises to give additional weight to the less populous states was necessary to form the union in the first place.
