Have you ever had one of those game nights where one of the guys insists that he knows the Settlers of Catan rules better than anyone else and keeps challenging everyone? And then your other friend gets frustrated and yells at him, and then your other other friend is like "this is why we never invite you over," and then everyone's storming out and you're like "I just wanted to raise some pretend sheep."

Welcome to the Nevada Democratic Convention, where everyone is fighting and nobody looks good. It took place last weekend. Hillary "won," in as much as she got the most delegates, but with all the shouting, threatening, shady deals, and shadier insults, everyone involved came out a colossal loser.

Things got off to a classy enough start at the extremely tasteful Paris hotel/casino in Las Vegas. But there was immediate tension over some obscure rules that are about as interesting as the debate over whether you should put one space after a period or two.

All you really need to know is that a minuscule number of Bernie delegates got disqualified because their paperwork wasn't meticulous, and party officials got pedantic over rules. These were lower-tier delegates, generally unimportant local-level people who pick the upper-tier delegates who actually go to the convention to nominate the candidate.

Of those upper-tier delegates, Hillary walked away with two more than Bernie. This was not a huge deal, if you are an unfeeling logical Vulcan. But most of the attendees at the convention were humans, and humans are prone to fits of unreasonable emotional tribalism.

That's why you've probably seen clips of people freaking out and shouting at the event, and heard that there was possibly some chair-throwing and cussing. Afterwards, party officials were bombarded with death threats.

This behavior is, of course, stupid. Almost as stupid as the untrustworthy system that selects our political candidates for us.

In a situation like this, it's nice to have a leader who can step in and calm everyone down and refocus attention on bigger problems. (Ecuador's recently been devastated by a series of earthquakes and desperately needs humanitarian relief.)

But that's not quite what's happening. Instead, both sides are digging in their heels: Bernie put out a statement that's surprisingly harsh in its indictment of the Democratic party, and then walked away from a reporter who asked him about it. His campaign manager accused the Democrats of "throwing shade"—yes, really.

Party officials, meanwhile, have been going after Bernie as a troublemaker.

Supporters on both sides have taken this as permission to get increasingly unpleasant with each other, as you have probably seen on social media if you haven't already judiciously blocked your political friends.

Just a few weeks to go until the Democratic National Convention in Philadelphia. Should be a real unifying time.
