Supposedly House of Cards is one of President Obama's favorite TV shows, which I find kinda intriguing.
My grandfather was in the army during WWII and afterwards he never watched War movies e.g., Patton, The Longest Day, etc. According to my father he thought they were trash misrepresentations of war. I'm not sure of this but they might have even exacerbated a little PTSD. Anyways, when I was a tot I felt a similar feeling for my father, a doctor. Whenever he would come into the den and a medical drama (Scrubs, Grey's Anatomy, etc) was on he'd usually tell us to change it. I have a feeling it was for the very same reasons that my grandfather didn't like to watch War films. The only potential exception to this was Everwood, but that show focuses on the drama of a family that just so happens to have a doctor dad, so I'm not sure it qualifies as a medical drama.
Now I'm not implying that President Obama should have PTSD about politics, but I still think it's interesting that he watches a show based not only on his line of work but also in part on where he works.
