A lot of people are buzzing about this blog post by Tom Bruschino, assistant professor of history at the U.S. Army School of Advanced Military Studies at Fort Leavenworth, Kansas. Bruschino was contacted by PolitiFact and asked to weigh in on Mitt Romney’s claim that “Our navy is smaller than it’s been since 1917. Our air force is smaller and older than any time since 1947.”

I encourage you to read Bruschino’s post in full, as it includes Bruschino’s full exchange with PolitiFact. But long story short, eventually PolitiFact rate’s Romney’s claim as “Pants on Fire.” After going thorough the substance of the claim, Bruschino is surprised. “My opinion, for what it is worth, is that since Romney’s base statement was factually accurate when it came to most numerical metrics, it would seem that he could be given credit for a half-truth,” he writes. In response, PolitiFact dug in with a defensive blog post.
