That’s because she’s really a mental midget.
I was just burdened with watching a youtube video of her using her "unburdened by what has been" saying for about 4 minutes in different speeches. I didn't realize that she'd used it that much. She must really like it and think it's brilliant. While I was pondering the stupidity of it and the showmanship that she tries to bring with the hand gestures that she uses while saying it, something came to me. Since she wants to pretend to be a deep thinking intellectual who is black, if someone could tell her that "Yabba Dabba Doo, Zip A Dee Doo Dah Day" is her "unburdened by what has been" saying translated into an ancient, lost African language, she'd be Yabba Dabba Doo-ing all over the place.
