Wow, is this ever misleading. Unless you break this down into “practising Catholics” and “Evangelical Christians”, the numbers are meaningless. The vast majority of those supposedly Catholic voters gained by the NDP are in Quebec, which is now a largely secular province. Most are nominally Catholic, but very few practice the faith. Same as “Protestant”, which includes such pro-homosexual, pro-abortion congregations such as the United Church of Canada, Anglican/Episcopalian and Prysbyterian (the latter two of which still have some traditional adherents).
There was an “Evangelical Christians” category? I only saw the ‘generic Protestants of all different churches and persuasions’ and ‘members of the Catholic church’ categories.
