There are only 2 states that split votes, Maine and Nebraska.
A bigger issue is states, NJ is one and there are others, that have laws on the books that their electoral votes will go to the winner of the popular vote.
However, there is some trigger mechanism in them so none are in effect at this time. I’m sorry I forget what the trigger is, but I’m pretty sure that as soon as it is pulled these laws will be challenged on constitutional grounds.
Now, I’d have to go back and read the relevent parts of the constitution to see if I thought they’d pass muster, but we must remember that term limits (passed as part of the “contract with america” by the Gingrich congress and signed by Clinton) was thrown out on the grounds that it imposed an unconstitutional requirement on congressmen/senators.
This is why I wish people would stop saying “we need term limits!” because we got them and they were ruled unconstitutional. If anyone really wants them for the federal offices we’re going to have to amend the constitution.
The law does not become effective until it has been passed by states totalling 270 EV.
Which will never happen.
The term limits measure was the one element in the Contract with America that was not passed by the GOP Congress (the contract had promised to bring the issue to a vote, not pass it).
Subsequently, several states passed term limits measures. And it was these that were challenged in court and declared unconstitutional by SCOTUS.
