Mitch McConnell, Mitch McConnell? Hmmm.
Who is this guy again?
Wait, isn’t he the new Senate Minority Leader?
There is no official position of Majority or Minority leader in the Senate. The last time (2000) we had a 50/50 split the leaders of the Senate negotiated an agreement on how to proceed. Trent Lott was Majority Leader by virtue of a Republican VP. More important committees were split 50/50. That's a far more important consideration and I don't think there's a Senate rule addressing that.
