The reason Pia left is because she did not inspire enough voters. It is that simple. There are many reasons and none of them have to do with women not voting for a beautiful girl! This debate always comes up on this show and any other with viewer participation.
She didn't show much personality and viewers failed to connect, myself being one of them. That is on Pia and not the viewers.
We get to know them through the clips they show and that is part of establishing a fan base. A good example is James and his passion for wrestling and all that created. We see him, we know him more now. No one saw much of Pia.
