I remember attacks in GWB for avoiding the Vietnam draft by taking service in the Air National Guard, which he may or may not have taken seriously. People of a certain age may still see National Guard as a form of draft dodging akin to “bone spurs,” but it’s hard to argue that for a man who spent 20 years there.
When I hear the dude was a teacher and National Guardsman for 20 years, I’m pretty sure that’s just a guy who took a second job because teaching doesn’t pay shit.
