I admit to being slow on the uptake. Thus, someone will have to explain how this works.

The U.S. Senate today confirmed Judge Brett Kavanaugh’s nomination to the U.S. Supreme Court. The tally was 50-48.

Two senators’ votes weren’t recorded. Sen. Steve Daines, a Montana Republican, was absent, attending his daughter’s wedding. Daines would have voted “yes” on Kavanaugh’s nomination. The other non-vote came from Sen. Lisa Murkowski, an Alaska Republican, who declared her opposition to Kavanaugh; she voted “present” when they cast the roll-call vote.

There’s a Senate custom that enables senators to pair their votes with those who cannot cast their votes in person. Murkowski teamed up with her friend Daines.

But … why? If Murkowski had voted “no” on Kavanaugh’s nomination, the tally would have been 50-49; Kavanaugh still gets confirmed. Therefore, this vote pairing had no tangible impact on the outcome of the Senate.

I guess I need to study more carefully the rules and customs that govern the World’s Most Deliberative Body. This one is a bit of a head-scratcher.
