Poll- Casey Anthony; Guilty of Capitol murder or first degree manslaughter?

Do you think she intentionally murdered her daughter or accidentally killed her and then hid the body to save herself from an aggravated manslaughter charge after the accident? As if maybe she was in the house high on drugs while the kid drowned in the pool.. if that happened, wouldn't she hide the body knowing she is going to go to jail for the child's death as a result of her negligence?
