I rarely listen to c-spam for that very reason - same with cnn.
After hearing all the disrespectful and vitriolic things said about Ronald Reagan upon his passing on that other line, I took a break from C-SPAN and could not stand it.
When I wanted some good election night coverage in 2004, I turned in on right until the calls reminded me why I stopped watching it.
Now, seeking a scan of how the news will cover the great event today, I am again reminded how crazy the callers on C-SPAN have become (the last caller accused Jeb Bush of influencing Bill Clinton to bomb Iraq in 1998!). I have amnesia sometimes; hopefully I'll never have to catch the channel on such a consequential event, which always brings out the worst from the Dem callers...
