::He is often called "Tingles" in reference to his comment about Obama in 2008 and it is a well known quote he made.  This particular mention today is probably due to the scuffle at the RNC when a MSNBC producer got upset that someone called Matthews "Tingles".  It is kind of ironic since Matthews made multiple references to Seamus last night.  I would say that it is not a violation of RS or V or NOR, but since it is used to mock Matthews it would be a BLP violation.
