Can't honestly say that I ever took that much notice of Ms Gillard or her career, beyond the initial bit of press coverage in my local press (Wales) about the Welsh connection. I do know this though. Every time I saw her on TV she came across as a thoroughly unlikeable character. She always sounded like one of those overbearing, insecure schoolteachers who feel the need to impose their will on their students. I can see why people responded negatively to her.
Not sure that testicles would have made any difference to those who disliked her? Being unlikeable isn't dependant on gender.
