They took the dollars that each candidate spent on advertising and divided it by the number of votes they received. They only highlighted the total dollars spent ($14.9M) and total votes received (5,235) by Jeb Bush, but didn't bring up the totals of any of the other candidates. For all we know, he could have spent the least amount of money. It's impossible to tell without the other candidates' totals. If I paid my friend $10 to vote for me, then I'd be spending $10/vote which all of a sudden sounds pretty good. Although, if I spent $5k to convince that same friend then all of a sudden my efficiency has dropped below Jeb's. EDIT: Was easy enough to find those other numbers. http://www.msnbc.com/msnbc/and-the-total-amount-spent-campaign-ads-iowa http://www.msnbc.com/msnbc/and-the-total-amount-spent-campai...
