It didn’t appear that way to me. If you look at the 1st vote results versus the second it appears most of Paul’s went to Romney but ALL of mccain’s went to Huck. Right?
You may be right. The article itself doesn’t clarify where Ron’s votes went.
Paul's people extracted a promise of three delegates to give over, so it's pretty likely they moved as a block. As to Romney's total improving, probably that was voters who were on the fence to begin with and put off by the nature of the deal.
