Special guest Amy Shafer joins us for the full show and highlights her fabulous research on the civil-military divide in America (and dishes on the Air Force Tops in Blue).

And Erin gets giddy over space marines. Stick around for our “Game of Thrones” preview!* *By which we mean fan-girl shouts of joy and anticipation.
