Some Dion supporters are arguing that we should stick with the leader we have because the learning curve for a new leader is long. It's a serious argument. We don't want to deepen the hole we're in with hysterical attempts to change direction.
But. Dion screwed up in such a range of ways. He:
* Continued to be a lackluster public speaker.
* Wasn't able to communicate his flagship policy to Canadians.
* Wasn't prepared for the election.
* Has been unsuccessful at fund raising.
* Didn't have an effective response to Conservative attacks.
* Was slow to get help from experienced Liberals.
* Didn't assuage doubts about his ability to lead Canada in tough economic times.
Polls showed that support for Dion was way behind support for the party. He dragged down the rest of the party. Canadians don't like him and don't trust him. He's had two years to get his act together. If Dion wants to stay, he should give us some reasons to think he'll improve.
