5-4 is also possible, since the 2 “senate” electors would be picked by popular vote of the state, and so you could win 4 of the 7 districts but still lose the state.
But you are right that the numbers are much less daunting.
But if they had done this in 2000, Gore would have won the election, as I think it would have swung 3 evs to Gore, giving him a 269-268 victory.
