I guess it depends on what you consider politics. It really is not part of the program, but some instructors will get off on that tangent (outside of the regular course) if you bring it up. Basically, just as Pathfinder stated, some revolutionary war history (and interesting to boot), and then a lot of time spent learning positions, how to use a sling, and how to really use that rifle. Completely different from shooting off of a bench. The program follows the Army Qualification Test, and is similar to high power competition.
Also, due to ammuntion costs, a lot of people use .22's to shoot it. I have built 2 10/22's with Tech Sights so the sights are just like what I have on my AR's, or M1A/Garand. But you can truly bring what you have. I have seen deer rifles, Mauser 98's, Mosins, SKS's, AK's, AR-15's, Robinson's, lever actions... and on and on.
Come on out and see for yourself.
