There's been a major power shift at Commander in Chief. ABC has brought in veteran producer Steven Bochco to take over show-running duties from series creator Rod Lurie. (How huge is this? Imagine if NBC had fired Aaron Sorkin two episodes into The West Wing's first season. That huge.) Although Lurie will retain an executive-producer title, ABC says he'll focus his energies on developing new projects for the network. And then abandoning them when they get on the air.
