I'd count Number One as being along the same lines as Sheridan himself - it's OK to be a politician if you've also been a soldier.

I do wonder where the Hague plot was going - Keeping Hague around has the same problems as a hypothetical opposition civilian leader; worse, since there's a clear chain of command. I assume he wasn't scheduled to last much longer past "Severed Dreams" even if the actor had been available.
