I’ve looked at several articles on this and cannot find any mention of McCain voted. I would guess that it was a 49-49 tie and Pence had to break thew tie.
Here is another article. https://www.msn.com/en-us/news/politics/senate-confirms-trump-court-pick-with-record-of-attacking-voting-rights/ar-AAAgpqO
Did McCain show up or not? Resign dude! You’re dead weight (unless you actually voted)
you can just check the senate vote tally:
and no McCain hasn’t shown up in all of 2018.
the senate is currently a 51-49 R majority. it’s 50-49 without mcCain.
