The way I see it, it's simply the Machine knowing that it's so secure in its web of fraud that they feel comfortable rubbing our faces in giving us the details in real time.
And the Milwaukee (and Madison) voters feeling that it is their RIGHT to cheat at elections.
One of the most frustrating aspects of all of this is that the Republicans refuse to cheat (not that I would have it any other way.) But the R party just lets this stuff happen and never says a word that means anything about it.
