This primary is begging for ranked choice voting. A winner take all delegate allocation tied to ranked choice voting ensures the field has both winnowing opportunities and a true majority of voters selecting the nominee. The present system of proportional allocation with its mix of caucuses and primaries, some closed to independents, is a recipe for disaster. It’s entirely possible that Sanders will continue to “win” primaries with just 30% of the vote. Whether or not one is a Sanders supporter, this outcome is neither a desirable nor genuinely democratic one. It is also likely to produce a contested convention, which would be the least democratic outcome of all.
Like Charles Blow, I also support holding all four early contests on the same day. This ensures that a black majority (South Carolina) and Latino majority (Nevada) electorate have an equivalent say to the white majority electorates of IA and NH. Making all four contests primaries is the fairest way to ensure every vote is counted (and quickly!) and everyone can participate regardless of their work or family time commitments. It would also help more diverse candidates stay in the race, so we never end up with an all white debate stage again.
While these two reforms were lost in the fight over superdelegates, they have to be implemented by the next primary cycle. Make the early round more diverse, and switch to a winner take all ranked choice method of delegate allocation. This is the only way to ensure the party nominating produces a unifying nominee supported by a clear majority of primary voters.
