Search as an election predictor

Adam Mathes has a series of posts at MLKSHK (1, 2, 3, 4, 5) showing searches from Iowa users for each candidate in the last month as well as the 2008 search results for a similar time period (and search was a good predictor for final results in the Iowa caucus).

Long story short: Adam predicts Ron Paul will win in Iowa but not much after and spoil the election for any other Republican candidate. I don't know if Adam is right or wrong, but it's an interesting approach and I could see it coming true.
