I used to. I have barely watched it the last couple of years, partly because I have sort of checked out of watching a lot of politics. C-SPAN isn’t only politics though.
I have seen amazing interviews on C-SPAN where I learned a ton of valuable information. An interview with an accountant stands out in my mind. I guess you can relate almost anything back to politics, but sometimes the interviews I just see as interesting topics. Discussions about education, religion, workforce, society.
Also, C-SPAN televises things that other stations don’t, and even if other networks are televising, the other stations have too much biased commentary.
I know many people who watch C-Soan at least once in a while.
Edit: if you don’t watch, you might want to check their website for topics, and you might find something you’re interested in. You can see the daily line up.
