Yes, but that means she vote her as a participant. As soon she does this, she has no vote.I know all of that but you are wrong about one thing - Monica vote for herself! When the vote start Monica is first and she need to decide to who will vote and there it is: "Vote for Miranda" ; "Vote for Abby" and "Vote for herself" ! So i am sorry but like i already say Monica actually is voting for herself
Steve even mentions, that Monica has zero votes.
You can see it that way:
Abby votes for herself as a participant, so she used up her vote for that.
It´s the same for Monica and Miranda.
The system is indeed a bit strange, but Monica has no benefits.
"Vote herself" means here: "Take part as participant"
But I agree, that the formulation of the sentence "vote for herself" is a bit misleading.
By the way: The pool is in the basement of Monicas house. Just saying
