In Montana, a House race has ended in a tie.
And the outcome of that particular race decides whether the Democrats or Republicans have the majority.
If the Democrat wins the race, they will control 50 of the 99 seats in the Montana House.
Under Montana law, the Governor breaks ties, and as a Democrat, Schweitzer's choice is obvious. (Under Oregon law, I believe a coin flip would break the tie).
Of course, there will be a recount, so nothing's settled.
