John Ibbitson in today's Globe & Mail shakes his head as much as I do over it - his take is from the point of view of a lack in strategic foresight in the decision to drop Garth Turner from caucus [Globe & Mail, MP's expulsion dark news for Harper, via Google]:
Regardless of the reason, the expulsion says nothing good about the party or the Prime Minister. Mr. Turner is a rare phenomenon: a conservative politician popular among middle-class suburban voters outside Toronto, that most precious of political constituencies, and one generally hostile to Harper Conservatives. They liked Mr. Turner's passion for lowering taxes and streamlining government, but equally his commitment to the environment and his socially progressive views. Mr. Turner was a Tory metrosexual, and the party needs all of them it can get.
I still don't know what to think, honestly.
As I've said previously, Garth Turner was a credit to the Conservative Party, and I don't think the party's fortunes are going to improve with his removal.
