So, let me make sure I have this all straight, because I am old and I have a lot of kids and they literally drain your brain power:
The DNC decided to listen to Bernie's supporters and make the Iowa caucus more transparent by agreeing, without opposition, to the rule change to make it a requirement that the IDP report the raw vote totals before and after realignment. At the same time, or relatively shortly thereafter, the DNC also did : waves arms magically : so that Pete would not become the DNC Chair. They loved their boy Pete so much they had to stop him from being chair. The Iowa Democratic Party decided to hire someone who had no business developing an app to develop an app specifically so they could somehow rig the results against Bernie Sanders. On caucus night, the IDP/DNC decided to destroy their own reputation, have literal hundreds of caucus sites fuck up, and refuse to report results until such time as they could rig this in favor of Pete. So, instead of outright rigging it for Pete, and not Biden who most of THE ESTABLISHMENT wants, they decide to throw the whole thing into chaos. Literally ruining Iowa's reputation and making it so it is very, very unlikely this dumbass state will ever go first again. Then, after days of confusion, they go OH SHIT THE RIGGING WE DID WASN'T ENOUGH, so now we need Tom Perez to come in and say that the extremely esoteric rules that we used to allocate Satellite Caucus results (a thing we've never, ever done before on top of never having to report popular vote totals) are possibly wrong. And all of this has gone off without a hitch, because Democrats are so good at literally everything, we can manage to rig a caucus with a literal paper trail. Because that totally sounds like Democrats. When I think "Democrat" I think "highly competent."
