What I mean is simply to allocate a state’s EV by Congressional district, then award the 2 Senate votes to the state as a whole.
Say in CA (using pre-2010 numbers), McCain would have won 23 of the 53 House districts, and of course Obama won the state overall. In that example, CA’s EV’s would be as such:
McCain 23
Obama 22
That’s the way Nebraska and Maine allocate Electoral Votes.
If a state decides to do that, they are perfectly free to do so. Nebraska and Maine select their electors that way now.
