Resolves N/A if the filibuster is not ended by the midterms. Otherwise, resolves at the parties that have a majority in the House and Senate, respectively.

If the Senate is 50-50, resolves R Senate.

If neither the Republican nor Democratic Caucuses have a majority in a chamber, resolves at the party of the majority leader in that chamber.

Resolves "other" if these conditions are somehow impossible to apply (e.g. independent majority leader, no midterms, house or senate no longer exist, all the congresspeople are abducted by aliens).
