It wouldn’t even matter if Kavanaugh admitted to doing these things, Republicans would still support him. They wouldn’t care just like they didn’t care about Trump admitting to sexual assault.
Republican support in general, yes. But it’s 51 particular Republicans that matter. Among that number, we have one with a record of standing up to pressure (Murkowski), one with a record of antagonizing Trump verbally, if not with votes (Flake), and one with a record of being a principled maverick a few years back and recently selling out for no particular reason (Collins). If two of those three were on board, Kav would already be confirmed. There’s a slim chance Murkowski and Flake will hold out. There’s even a chance Flake has no intention of voting for Kav, but is dangling the possibility so that this process drags out and causes maximum political damage to Trump. But my money’s on eventual confirmation too, even with a positive paternity test on an underage victim from last year. Murkowski’s 50/50 though.
And even if he isn’t confirmed, he’ll become a cause célèbre among the sort of conservatives who use the term “Borked” to refer to decent, qualified justices who get screwed by politics, even though they were merely the DOJ Hatchet Man who helped obstruct justice by not having enough scruples to refuse Nixon’s orders for the Saturday Night Massacre like his immediate two predecessors. Well, okay, they tend to leave off that part of his resume.
