Ties happen from time to time. Here's one I could find [1], and I recall one that I can't find maybe a decade ago in coastal northern california that they resolved by throwing dice.

I think it wasn't so much that ties aren't possible, but that ties don't mean "no one wins". If you make one district safe and three districts are a coin toss between your two rivals, one of them has much more power than you in the end.
