Just because Barack is mentioned more times, does not necessarily mean that he is more popular. It just means that he is more mentioned.
I'm not saying that Barack isn't more popular, but it is possible that more mentions also means more negative mentions.
It is an interesting hypothesis though. You could call it their buzz score. If it happens to equate to a political win, then it would really be worth writing about. :)
