This is an interesting proposal, long overdue and in keeping with the democratic reforms made by the party in its candidate selection process over the years. The superdelegates have been defended as a way of resolving close races, but they really are nothing more than a hedge for the party insiders to ensure that the party’s grassroots cannot take over the process.
The fear is that the Democrats could have a repeat of the 1972 primaries, the first in which the primaries actually mattered, and nominate a new George McGovern. That fear, of course, is overblown and ignores the historical record — as I wrote in 2004 and David Sirota wrote in his book Uprising. Nixon won that election for a lot of reasons, but not because McGovern was some kind of crazed lefty. He won because he was an incumbent that ran a smart race against a fractured Democratic Party and a candidate that made more than his share of mistakes. The Democratic establishment was as much to blame for what happened as the McGovern campaign.
The Democrats, as the 2008 election showed, are at their strongest when the grassroots is empowered and engaged. Altering the rules makes sense for the party.
