I was very busy at work yesterday and didn't follow along with this topic, but did catch up quickly just now and I spent last night reviewing the events of yesterday.
If you continue to support Kavanaugh's nomination at this point, then your motivations appear to be purely partisan, full stop.
His opening statement, his ridiculous answers to legitimate questions, his contradictions (arguing against testimony from Mark Judge, but then deflecting questions about Judge, saying in effect 'go ask him'), his outright lies (didn't watch Ford's testimony, oh but oops, WSJ reported that he did). His belligerence, his close-mindedness, his dismissal of an entire political party, his conspiracy theories about Clinton-backers out for revenge (dude, no one cares that you gave Clinton a much harder time than you are willing to endure, they just point it out now to fully reveal your hippocracy). None of this should be tolerated in a county judge, much less an appellate judge or supreme court judge. Irregardless of these allegations, this person is not fit for the SCOTUS.
He should have his nomination pulled, he should be impeached from the DC Circuit Court, he should have any law licenses revoked, and if he is appointed to SCOTUS, he should be impeached at the first opportunity. There is no argument that changes these realities.
