Olberman and Matthews are talking about the "canary in the coalmine" victory of the Dem challenger over Nancy Johnson in CT.
Olberman and Matthews aren't experts in elections.
In fact, I don't know what they might be experts in.
(I'm being serious here) During an interview with Brian Lamb on C-Span, Keith Olberman revealed that he had sustained a serious head injury whilst trying to jump aboard a moving train. Brain damage and all that.
I have no idea what Matthews problem is, other than slobbering.
