I don't follow. A 269-269 split, given how the states have broken, is staggeringly unlikely. Multiple states would have to be flipped, and since US elections are so distributed, it's unlikely for SCOTUS to find in such a way as to change the results of more than one of these states, if any.

And even if the election somehow ended up in the 12th Amendment case of the House deciding: the House is trending Democrat control.
