I really wonder about the extent to which Parliament itself should tell caucuses and parties how their internal politics should be governed. I really do. Historically there's been a big difference between parties both within Parliament, outside Parliament, and the relationship between the two.
In some of the parties there's been an enormous grassroots power. I think back to the CCF-NDP government that I worked for in Saskatchewan in the 1960s. There was a tremendously strong constituency organization as well as a government.
By and large the major parties in Canada are organized around their parliamentary representation. I think in that sense the parliamentary representation should have a pretty strong voice in deciding a party leader and other related matters.
