Alberta's Conservative dynasty

Alberta's Tory dynasty will celebrate 40 years in power Tuesday, marking the second-longest majority rule in Canadian history.

It was the summer of 1971 when they first took office: iconic Doors frontman Jim Morrison had just been found dead in a Paris bathtub, the Pentagon Papers were making headlines and Gloria Steinem had just delivered her revolutionary Address to the Women of America.

Led by 43-year-old Peter Lougheed, the Progressive Conservatives won 46 of the 75 seats in Alberta's legislature, ushering in an era of majority rule exceeded only by the Nova Scotia Liberals, who dominated that province for 43 years, ending in 1925.

Even experts can't agree on how they've done it.
