It seems he is not an eagle Scout but Rick Perry thought so when he wrote his book, On My Honor.
Romney is not an Eagle Scout
Perry claimed Romney as an Eagle Scout, when he actually wasn’t.
Interestingly, I found that Perry and Huntsman are both Eagle Scouts.
Huntsman is a very dark horse; like Mitt he is a Latter Day Saint, but Huntsman might actually beat Mitt out in hypothetical performance as a Republican ham sandwich. Huntsman does not have the conniving experience of Mitt so there could be more hope.
