That's kind of how it works though, unanimous consent requires...unanimous consent. And that is only required to expedite the process. The default is a full vote and confirmation, where everyone gets to interview the candidate, present arguments for or against them, etc.--the democratic process. Yes, refusing to consent unanimously can be used as a "stall" tactic, but there really should be no less than unanimous consent for Senate to be able to act outside the normal democratic process, even if it means shitheads sometimes get to be shitheads.
