Here's somethin' for ya:
Just pretend that it's possible... and it's proven beyond any doubt that a state is tied.
And the state (or a CD) just happens to hold the balance to the election:
What happens? Does it go to the house? Or does the elector just decide?
(then the election really could have hinged on one vote!)
Under the US Constitution, each State determines the manner in which its electors are
appointed. At present, each State chooses its electors by statewide plurality popular vote
(except Maine and Nebraska, which choose some of their electors on a CD basis).
Each state election law likely has provisions for breaking ties, which may or may not be specific to
Presidential elections. Missouri elects its electors by CD (but based on the statewide vote). In
case of tie, the General Assembly would determine the winner in each CD. I couldn't find any
presidential-specific law in Texas. But Texas law provides for runoff elections in cases of
tied plurality elections. A presidential elector is an officer of the state, just with a very specific
and limited power, so I see no reason why the general law would not apply.
