West Wing cancelled.
This nicely averts the problem of which president to choose - do you try and make a Republican drama, or do you go with a stale Democratic plotline.
I personally don't think a Republican drama could ever work in fiction, for much the same reason as Kim Stanley Robinson says you can't have a Right-wing utopia - Utopias are by definition about progress, while right-wingers are at best wedded to the status quo, and at worst about turning the clock back.
A Republican "West Wing" would bomb, and deservedly so. Somehow, I can't seen an exciting drama built around tax cuts and illegal wars.
