If Lisa and her friends are unhappy with any of the top ten guys they only have themselves to blame.
They could have booted Robert before he got to the position of having the public campaign for him to win in order to stick it to Lisa and her friends.
Lisa does not come across as a likeable person to me.
She is looking for a "perfect" man without giving any clear indication that she is anywhere close to being perfect herself.
You choose your friends and the ones she has chosen speak volumes about her imo.
