Thirty per cent of Canadian voters (over 5 million) have little to no partisan attachment. By comparison, only eight per cent of U.S. voters swing their party support, and thus the elections. A large non-partisan voting bloc explains the 2015 shift from orange to red, where in a span of three weeks, 1.4 million voters changed their mind from NDP to Liberal. This provides the perfect environment for strategic voting to swing elections. After four years of a majority Conservative government elected against the will of 61 per cent of Canadians, strategic voters became a major voice in this election.
