It looks like Trump knows Kavanugh is DONE, and he has been using him to rile up his deplorable; for the purpose of providing himself with cover for his many sexual abuses. As it always is: Trump is looking out for himself.
From Elise Jordan, a Time columnist.
"I certainly think it could help Donald Trump if Kavanaugh doesn’t get confirmed because he [Trump] is a ‘victim. That’s his number one message — about his own victimhood. And, ‘The elites did this to me, this is what they’re trying to do you. They’re out to get you.’ So yes, I do think that he might not be Brett Kavanaugh’s best friend right now."
