There is a distinct possibility, though I refuse to believe it till I see it. The last time we had four elections in so short a time (1962, 1963, 1965, 1968) the fourth ended in a majority government. Already the PM has explicitly asked for us to be given a majority, letting the word slip once but emphasizing stability. Chretien didn't get his 1997 majority (in the Balkanized '90s) until the last 10 days of the campaign.
Well observed. The similarities go deeper: the first election saw the ruling party reduced from majority to minority rule and the middle two elections saw the former opposition rule with minority governments while the formerly-ruling party squabbled bitterly over its leadership (Diefenbaker and Stanfield).
It's worth remembering, however, that the fourth election saw the ruling party replace its leader for a new, charismatic bachelor named Pierre Trudeau. His eponymous mania, combined with his sangfroid at the St. Jean Baptiste Day riots, won him a majority. Anyone see that happening with Harper?
