There is also a rather critical column by Dan Lett on Swan's decision to step down. Now I agree that it makes for a less interesting race, but it's a bit harsh to criticize Swan for his choice. I think this comment to the column sums it up admirably:
I think that Andrew Swan should be applauded for his realistic assessment of his situation. It is unlikely he could ever have come up the middle. It is one leadership convention too soon for him. In the process, he has likely curried some serious favour with Mr. Selinger, which isn't a bad thing.I also doubt that this harms Swan's future prospects as much as Lett thinks it does -- I hardly think he has "closed the book on future leadership bids". We haven't seen the last of Andrew Swan by any means.
