Choosing the party leader: should it be left to the caucus?
While a party's parliamentary caucus may be the best body to decide when a leader should go, its members are not necessarily the best group to decide who should be the next leader. For one thing, they may be more interested in choosing someone who will help them get re-elected personally than in winning nationally.
