A leader from Quebec boosts the fortunes of the Liberal party in that province. This, in turn, has helped make Quebec the veto player in twentieth-century Canadian elections and the Liberals the “natural” governing party. Although Quebec is no longer as critical as before, a leader from the province still makes a big difference. Full impact from the pattern requires more than one election to unfold. Patterns outside Quebec are similar, if fainter: the Liberal party is not punished for choosing a Quebecker and may even be helped. The early success of the pattern moved the Liberals to alternate between Quebec and non-Quebec leaders, such that the party is now led by a Quebecker more often than not. Maintaining alternation has never been easy and is only getting harder.
