I mainly watch C-Span and PBS. Hate to admit it, but PBS usually has the most insight and seems least partisan. Good for public television. The Americans do it wisely, having the funding of PBS linked directly to audience donations which requires them not to alienate their viewers. The CBC and, even worse, the BBC, are a run by a clique of leftists and don't even make a pretence of objectivity.
I particularly enjoyed the commentary of David Brooks, the New York Times token conservative columnist. Mark Shields played the role of the openly liberal opposition, and he was OK, very smart and well-informed, though he seemed to lack Brooks' ability to see the other side's point of view even while he disagrees with it.
For instance, just after Zell Miller's speech, we return to the booth and Brooks is grinning away with what he admitted was a "guilty enjoyment" of the speech (my reaction too, they I don't remember any guilt) while he acknowledged that it was a polemic that gave no quarter and maybe went over the top on occasion.
He is an excellent spokesman for the conservative side.
