In the November 2004 United States election, one of the issues up for a vote in the state of Colorado was known as Amendment 36. It was a ballot initiative for an amendment to the state constitution. It would have changed the way in which the state apportioned its electoral votes. Rather than assigning all 9 of the state's electors to the candidate with a plurality of popular votes, under the amendment, Colorado would have assigned presidential electors proportionally to the statewide vote count, which would be a unique system (Nebraska and Maine assign electoral votes based on vote totals within each congressional district). The amendment did not pass.
