I'm 43 and my television watching pretty much parallels yours, with the addition that I like some of the cable channels' original programming and I also keep News 12 NJ on in the morning while getting ready for work but only really pay attention to the traffic and weather.
I'm a "market intelligence analyst" in the financial services industry by trade so a good part of my day every day is spent reading domestic and foreign newspapers, financial and economic trade publications, and other stuff of a "newsy" nature. If something of a political nature strikes my interest I'll read it but I'm not a political news hound the way I was when I was younger (I can't afford to be time wise).
I listen to Bloomberg, NPR, or one of the Sirius political talk shows during my commute (if I'm not listening to a podcast, usually realted to American history, or a book on CD from the library - currently Coolidge by Amity Shlaes - good book).
If I watch anything political on TV it's generally CSPAN and that only occasionally and with no regularity.
I never watch CNN, FOX, MSNBC. If I want to read a comic book I'll just go read one.
ETA: It just occurred to me that I do watch one of the three cable news channels for election coverage or "continuing coverage" of a big news event (Boston Marathon bombing, school shooting, & etc...)
