Trump: "We're making a huge mistake and we need to hurry up and make it while we still can."https://www.washingtonpost.com/politics/white-house-plunges-into-tumult-amid-crises-over-kavanaugh-and-rosenstein/2018/09/24/06981220-c016-11e8-be77-516336a26305_story.html
But I could be reading this wrong. Maybe he meant "call it" in the sense of an emergency room doctor who finally gives up with the defibrillator.
In other words, end the debate and do an up or down vote now. Trump thinks (likely correctly) that at the end of the day, all of the GOPers will fall in line and vote "aye."
To get him in position for self protection before he gets exposed by Mueller and many others. kavanaugh is a serial liar , corrupt, and possible a sexual predator and maybe rapist , who trump and the kgop refuse to have the FBI investigate him. That should be a huge red flag they don't want the FBI involved, because he'll be exposed even more. They don't care if he raped women, and are protecting a possible rapist for their court position for themselves.
