The odds on Kavanaugh’s confirmation are higher now than they were before the delay. From John McCormack at weeklystandard.com:
When Arizona Republican senator Jeff Flake insisted on an additional one-week delay of the Kavanaugh confirmation vote in order to allow the FBI to conduct a supplemental background-check investigation into allegations of sexual assault, many Republicans feared that it would accomplish nothing other than provide time for more people to smear Kavanaugh with new false allegations.
In fact, the delay has actually helped clear Kavanaugh’s name.
