The CCF was formed from an amalgam of farmers cooperatives (yes, like the Grange, considered socialist in America at the time of it's inception, but La Follette's programs for Wisconsin would be closer to the mark), trades union associations and actual, real live, doughnut eatin', hockey playin' Canajun socialists. The CCF was formed in 1932 in Regina. The Labour member for a riding in Winnipeg, one Mr. Woodsworth, was chosen as party leader. In the Regina Manifesto (1933), they called for the nationalization of key industries, as well as the social programs i've already mentioned. They pledged to work for a peaceful elimination of capitalism, and shortly after issuing the Manifesto, rejected communism.
Their power in the prairies came from the agricultural and industrial failures in the period known in the United States as the Great Depression. Plutocracy had been in heady ascendency right up until 1929. The government had encouraged large scale agriculture in the praries, and no consideration had been given to the climate and ecology of many of those regions. The Red River valley in Manitoba was a particularly accute example--the entire eco-system collapsed and disasterous cycles of drought and flood succeeded one another in the generation before the Wall Street crash.
Many of the immigrants to the praries had been Germans (lots of charismatic sectarians there) and Ukrainians, and they brought the memory of bloodily oppressed European socialism with them. Cities like Manitoba, Winnipeg and Calgary were in a rush to industrialize--both the United States and Canada profited greatly from what the European world knew of as the Great Depression, from 1875 to 1893. European capitalists with money to invest looked to North America for oppotunities, and liked what they found. The true story of the "wild west" in America and Canada has never been told, and likely will never be, because macro-economics and venture capitalism don't make for good cinematography.
When trades unionists formed associations and farmers started cooperatives, the west was a natural place for success for such organizations. The immigrant and the child of the immigrant were familiar with European socialism and trades unionism. When the hard times hit, they hit hardest in the west. The CCF was a natural, a shoo-in.
But the Liberals and the Tories stood not upon the order of their going, and soon were painting the CCF to be as red as the most scarlet political rhetoric could make them appear. Despite historically and repeatedly rejecting Communism, the CCF finally abandoned the Regina Manifesto in 1956. By then, it was too late.
As for New Democrats, who knows what evil lurks in their hearts and minds, apart, of course, from Lamont Cranston? The Mountie, who has resolutely denied being a New Democrat, or my sweetiepie who never has admitted to being a New Democrat, would best know the answer to that one--neither of them being New Democrats, and all. Neil Young's daddy was a New Democrat, mebbe he could tell ya. Given the hounding which the CCF suffered, with sufficient success to drive them into the parliamentary wilderness (i'm sure i'll be corrected if i am wrong, but i believe a party needs to seat 12 members in Ottawa to have standing), i rather doubt that the New Democrats would ever publicly adhere to anything like
the Regina Manifesto.
