Turner & The Liberals: A Marriage of Convenience?

I know that lots of people in the Liberal camp are excited about getting Garth Turner on board. In a minority situation, every seat in your column helps - so I can certainly understand the feeling. That said, Turner's maverick rep and his small "c" conservative position on a variety of issues might make him a troublesome fit with the Liberals. I cannot shake the feeling that both sides need each other for pragmatic reasons more than they have suddenly discovered some deep ideological commonalities.
