I don't see it as bias towards Patrick so much as bias toward a female winner.

If they want a female winner but want a token male in the final then Patrick is the obvious choice based on what seems to be his popularity with the voting public.

Well it does if we take into account that they have the voting stats......she may be pulling in the most votes and can withstand a bottom placing.

High scores yet being in the dance off suggest his support is not all that much.
