On November 5, voters in Colorado rejected a ballot measure establishing top four primaries and ranked choice voting in general elections.

Proposition 131 aimed to eliminate party primaries, and instead all candidates, regardless of party, would compete in an open primary.

The top four finishers in each race would advance to the general election, where voters would rank candidates for each office in order of preference.

If one candidate were to receive more than 50% of the vote, he or she would win.

If not, the last place finisher in that race would be eliminated, and the votes would be reallocated to the candidate the voters rank second.

The elimination process would continue until one candidate had 50% of all the votes cast.

As of 9:00 a.m. November 6, with 73% of the precincts reporting, Proposition 131 failed 56% to 45%.
