Understandably, perhaps, as your candidate's campaign can be confusing about that, shifting from bashing superdelegates to stealing superdelegates -- and even pledged delegates, somehow.  

This is when they cannot be taken seriously. Professional campaign staff ought to know the difference.  Pledged delegates represent votes cast.  So, you surely cannot mean what you wrote of them.

It should change to make the party more like the Democrats it is supposed to represent (except that is not what the political parties do in practice).

It is not enough to show up every four years to vote or maybe attend a rally. That will not change the Party very much.

Something that seems very overlooked in the reporting on this campaign is that Clinton is winning by a goodly margin among voters who are actual registered Democrats. These are people who have taken the most basic step in Party membership- they declared a Party preference when they registered to vote.

IMO, what the GOP mess reminds me of is not unlike the stories about the Salem witch trials.  Whether the pure conservative (try Cruz, e.g.) is standing on supposed principle to shut down the government to satisfy his unforgiving positioning or whether the hysterical TeaPots drove so many to similar hysterical positioning or whether that bunch is now prepared to burn itself down because none of them appear capable of working together anymore may not matter to us now.  In fact, Democrats should gain handily IF the Repubs keep driving their fiasco further.  I'm actually beginning to wonder how small that Repub convention will become, in the name of purity, as official after official denounces the process and announces intent not to attend.

The problem with political purity on either side, the problem with almost mixing politics with personal beliefs to the extent that deals/compromise/resolution must be considered evil or close, the problem with a sect or faction of either party refusing, ultimately, to work with other party factions in the interest of all the members IS that the exclusionary view isolates itself with its self-absorption and may well move those whom they are trying to convince in the opposite direction.
