When the kids tell their parents what a great man he is, and how much they really, really like their new found TV friend,
the parents will find that to be a fall back position when Obama is challenged for real.
The speech is using the children of the nation to help protect Obama in the coming weeks and months.
Obama will give an innocuous enough speech of little importance, but it will clearly be a propaganda vehicle, designed to implant 'hope' in the eyes of children, who as toy makers know, influence their parent's buying habits, and can therefore influence the resistance to the crap the parents will buy from Obama.
It is child abuse.
