Those stubborn ol' viewers will vote the way they want no matter how much the judges try to sway them. I remember one year (not sure which year, but I know Jennifer Lopez was one of the judges,) they actually scolded the viewers for "voting wrong."
And back during the Minaj season they even rigged it so the boys in the "top 10" would be weaker than the girls, insuring a girl would win. Can't even remember who that was now.
OMG I’M SHOCKED. Gabby’s pissed.
I think that was the Candace Glover season. They got their female winner, but I believe she was the least successful winner ever.
