If it makes people feel better, go for it. The system was set up against the sort of corruption that people blame on superdelegates (nobody knows history lol), but it's a timely change that will give voters an illusion of greater choice.
But one the other hand, this is also a reflection of populist and tribalist stirring. Consider that political parties are critically weak and that "going public" has its own drawbacks, like a lack of continuity in party ideology, and the danger of crises of leadership, with power struggles akin to what we saw with the Tea Party. I don't think this bodes well for the people, I think we're mostly full of shit and stupid.
