Here is a third clip of school children Singing for Obama (first Berman Post: School Children Taught to Praise Obama?, second Berman Post: Another Video of Kids School Kids Singing About Obama). This one reportedly took place at a PTA meeting meaning that the parents were likely watching. Not sure if that makes this better or worse; better that knew, worse that the parents saw nothing wrong with this.
