For me the real story from Ames is the 501 people who ponied up 35 dollars (one way or another) and then voted for Ron
Paul.
I would bet that Paul came in second to Huckabee for voters who pariticpated on their own accord for a candidate. Romney and Brownbeck underperformed in that regard.
5th place is still 5th place, but Voter enthusiasm counts as well, and those two had the most enthusiastic voters.
