Peter Lougheed. (PC) Premier of Alberta 1972-1984
John Manley. (LPC) Liberal MP, served in multiple cabinet roles under Chretien and Martin.
Preston Manning. (R) Leader of the Reform Party from 1988 to 1999, Leader of the Official Opposition from 1995 to 1999.
Lawrence Decore. (LP) Mayor of Edmonton in the '80s, Leader of the Alberta Liberals from ~1990 until his death in 1999. In 1993 his Alberta Liberals nearly unseated the governing Tories.
Roy Romanow. (NDP) Premier of Saskatchewan in the 1990s. Headed a provincial NDP that was known for being more pragmatic and successful than it's federal counterpart.
Correction:
Decore was Liberal leader only until 1994. Interestingly, in the '93 campaign, it was Decore, not Klein, who first started preaching fiscal austerity, even promising "massive and brutal cuts", a phrase most people would now associate with Klein.
re: Manning, I dunno. I've always thought there was something amateur-hour about the guy. I remember how he made SUCH a big deal about how his MPs were gonna forego the "gold-plated pensions", and then, one by one, they all quietly lined up to re-enlist.
I realize politicians often break their promises, but there was just something really ham-fisted about the way Reform ditched that one. They couldn't even claim "Well, we hadn't seen the books before we got to Ottawa", since MPs' salaries and pensions are public knowledge.
I recall that the first MP to bite the bullet on pensions actually cried in front of the media, and said that his wife sat him down and said that they couldn't afford to retire comfortably without the full payment. It was pretty pathetic.
Manning has long had the dream, inherited from his father, of killing Toryism in Canada and replacing it with something more like American-style Republicanism. To be honest, the whole thing seemed more like an alternative history thread("Make Canada more right-wing") than a realistic proposal. Even Harper hasn't outlawed abortion, gay marriage, or reinstated capital punishment.
