I agree Justin is not ready, not so much too young but that he doesn't have enough experience, or hasn't really revealed his strengths.
I really wish the people who are starstruck over Ignatieff would take a harder look at him. I think he is in position to be the most likely pick among the tiny number of Liberals that actually have a say in who the leader will be. His whole life consists of a series of scenarios wherein he routinely ditches his family, friends, colleagues in order to make a move up in the world. I don't think he has much of a conscience left, and I don't want him leading our country. I think I'd vote for Stevie first, and that's scary.
