Last night on the late news on our local station they had a story about the YouTube and like posts about all the little kids that can be seen saying "Obama".
Then they had a child development expert explain it. Seems that "Ba" and "Ma" and other 'ah' sounds (like "Pa" and "Da") are the first ones kids learn. They babble them (and get really positive feedback from the adults around them). The sounds become friends to little kids. Consequently O+Ba+Ma is something they like to hear and say.
I have to wonder, how much of that childhood affinity to O+Ba+Ma sounds is still impacting the young adults that seem so drawn to Sen. Obama? Is it really as simple as childhood babble affecting our political process? I think it would explain a lot.
