Which I don't see ever happening.
The idea sounds absurd anyway, and unfair to the voters in those states. Suppose NJ were to go 60% for Obama, but McCain wins the national vote by a small margin. Then all of NJ’s electors would vote for McCain, even though a large majority of voters there chose the other guy?? Seems like it is disenfranchising the voters of that state.
It could have bit them in 2004 also. Suppose Kerry had taken Ohio but Bush still got a majority of the vote nationally. Under the existing system Kerry would have had 272 votes, and victory. But under this new proposal, NY would then have had to give all their EV’s to Bush, and he would have won! Am I wrong? Hmm, maybe it’s not such a bad idea after all....
When they enacted this law they must have figured the Dems would be winning the next election. Not so fast.
