Last week, British Columbia held an election for its provincial legislature. The two major parties in British Columbia elections are the New Democratic Party and the Liberal Party. Before the election, most observers expected the New Democratic Party to win a majority in the legislature. However, instead, the Liberal Party won. Because the Green Party had candidates in 61 of the 85 districts, and because the New Democratic Party is considered to be “left” of the Liberal Party, some commentators wrote that the Green Party had “spoiled” the election for the New Democratic Party.
Canada, like the United States, does not have proportional representation and does not use ranked-choice voting.
Chad Skelton, writing for the Vancouver Sun, here reports his research into whether Green Party voters would have supported the New Democratic Party over the Liberal Party, if the Green Party had not been in the race. To his surprise, he found that the Green Party campaigns did not cause the defeat of the New Democratic Party.
