...as the Liberal Party is far too far to the right economically for him to fit in. He's a quintessential tory. People always get confused when they saw him in the Progressive Conservative party, but that party was traditionally full of people like him as well as economically right-wing people. It had been a coalition between red and blue tories.
Essentially he's a red tory, in the traditional sense, not in the modern sense that moderate or socially liberal (but economically right-wing) Conservative MP's are somehow "red". He is conservative, as in doesn't like change. And therefore he doesn't like the way that the NAFTA agreement have hurt Canada's previously traditional pro-nationalist institutions, and thus hurt Canada's identity and sovreignty. He doesn't like GMO's, becaues he prefers to be cautious, and thinks they are un-healthy. Apparently he's moderatley socially conservative, ie: doesn't approve of Gay Marriage. But that said, he's not a religion thumper either. I'd say he's like Diefenbaker and other real "red" Tory leaders, who are somewhat infavour of a mixed-economy between socialist and free enterprise solutions, but still in favour of traditional institutions like the Monarchy.
