The Liberal Party of Canada has been out of power for nine years now, since January 2006.
That's when a slew of Liberal scandals ("sponsorship" and the leaking of planned income trust tax provisions, to name just two) handed Stephen Harper and his new-look, hard right (no longer Progressive) Conservatives an unearned victory.
The Liberals have been through four leaders since then, counting interim leaders Bob Rae and Bill Graham, and are now on their fifth.
The party of today has, quite literally, a new generation of leadership.
The current leader was a young scion making his way in the world, far from politics, when the scandals that brought down the Paul Martin/Jean Chrétien Liberals happened.
