The most bemused man in America must be former Speaker of the House Newt Gingrich. In response to a question at a campaign stop in New Hampshire, former Florida governor and current presidential candidate Jeb Bush pronounced Gingrich’s idea of a moon base as “pretty cool.” The former speaker must be asking himself, where was that kind of support in 2012 when he first proposed building a moon base by 2020? Indeed, a number of recent developments have made the once ridiculed idea cool again.
