A couple of years ago I tried to sign into C-Span with my computer and could not. They have a very crufty system. And Howard, I was attempting to access material recorded decades ago. If you can do that without an account, then that has probably changed because I couldn't get at it.
I must admit I do watch C-Span once a year. That's when the President of the United States (who ever it is) gives his state of the union address. Only because C-Span doesn't have anyone talking before the address.
