The Nevada Democratic Party issued this post, which states in part:

Based on the county convention results, Bernie Sanders had 2,124 delegate slots to the State Convention and Hillary Clinton had 1,722 delegate slots to the State Convention. On Saturday at the State Convention, after all of the alternates were seated, Hillary Clinton filled 1,695 of her delegate slots and Bernie Sanders only filled 1,662 at the State Convention — giving Clinton a 33-delegate margin of victory.

But what about those denied credentials?

Six of the 64 potential delegates were seated as delegates after investigation. The remaining potential delegates were ineligible for two main reasons: 1) They were not registered Democratic voters in Nevada by May 1, 2016, and 2) Their information — such as address, date of birth and name — could not be found or identified, and they did not respond to requests from the party and campaigns to correct it. Only eight of the ineligible delegates even attempted to register at the State Convention.

My emphasis. So in fact NONE of the goings on had any bearing on the result of the Nevada State Convention. Even if the 8 Sanders delegates had been seated, Clinton would have won. And the delegate split would have been exactly the same.

Still an issue on the quorum for the Rules Committee, but obviously the delegate selections rules could not be amended without DNC approval so even that is just a minor procedural point.

Long story short, no there there on this.
