You're talking about Rep. Murtha, right?
No, I doubt he meets the technical definition of libel. I'd rather see him lose his seat in an election -- that's where these things should be decided, not in court.
The left wants to criminalize speech that they don't agree with, or at least tie up their opponents in court. I don't think those of us on the right should go down that path with them.
Does that mean, "No?"
