if the liberals made an error here, it's that they weren't firm enough - they should have turfed her right out of caucus, immediately, due to gross dereliction of duty.
i know the tory media is going to howl that the pm acted unethically, but i hardly think most people are going to walk down that path when presented with the evidence. there's no question that the liberals have managed this terribly, and in the process turned a non-issue into a headline. they should have acted decisively and firmly changed the channel; as it is, they let it fester and erupt. as it is now? let them have the investigation. it doesn't look like anything happened.
