I suspect that it’s McConnell who’s calling the shots and grassley the spokesman. The turtle has traditional media fear so this is likely just theater to avoid pc perception of anti-female bias. The delays are infuriating but as long as confirmation occurs well before midterms who cares. unless they’re holding something back, she doesn’t appear to have a smoking pubic hair on a coke can, i think they have all 51 R votes.
Kavanaugh has to be seated before the end of this month in order to be seated for the next coming court. That is why the delay is bad. Before the midterms is not good enough.
