Leaving the contest open until all the way until Labor Day, however, would result in a lot of frayed nerves without much time to soothe them before the November election. In a New York Times op-ed, Bredesen lays out his thoughts on a "super" primary to settle the matter by the end of June:
Here's what our party should do: schedule a superdelegate primary. In early June, after the final primaries, the Democratic National Committee should call together our superdelegates in a public caucus.
Of the 795 superdelegates, over 40 percent have not announced which candidate they are supporting; I'm one of them. While it would be comfortable for me to delay making a decision until the convention, the reality is that I'll have all the information I reasonably need in June, and so will my colleagues across the country.
There will have been more than 20 debates, and more than 28 million Americans will have made their choices and voted. Any remaining uncertainty in our nominee will then lie with the superdelegates, and it will be time for us to make our choices and get on with the business of electing a president.
This is not a proposal for a mini-convention with all the attendant hoopla and sideshows. It is a call for a tight, two-day business-like gathering, whose rules would be devised by the national committee, of the leaders of our party from all over America to resolve a serious problem. There would be a final opportunity for the candidates to make their arguments to these delegates, and then one transparent vote.
