The desired result is a party that cleans up its act, reforms under new leadership, and then gives all candidates a fair shot, even if those candidates are populist insurgents like Sanders and Trump. I have some respect for that, and it's even appealing to a degree. But the thing driving the insurgent popularity is the long-term weakening of the parties. What that creates is a charisma vacuum, and I think we'll be lucky if we get another principled candidate like Sanders next time. It's cult of personality from here until whatever's next. Unless something drastic happens before 2018, democratic candidates are only going to become less moderate. It's why people are whispering about a leftist Tea Party.
