McConnell didn’t want Kavanaugh because he wanted the confirmation done quickly. Kavanaugh had such a long track record as a judge and in political circles that his vetting process would take a long time.
Oops. Barrett would have been a breeze. Kavenaugh wasn’t even on tje list of 25. He was added later when he said president’s can’t be charged for anything in office.
But in the long run it wasn't his record as a Judge that the Democrats cared about. They wanted his White House documents, trying to drag the hearings out, and when they couldn't get all of those, they dragged a bimbo out. The Dems stalled his confirmation to the Appeals Court from 2003-2006.
