 During most of the postwar period, the CCF and its successor, the New Democratic Party have dominated provincial politics with Douglas, Allan Blakeney, and Roy Romanow all serving long periods as premier and becoming national figures.Urbanization since the Second World War has altered the provincial economy away from its agricultural basis, and there has been a steady migration from farms to cities and towns.There was a corresponding shift in the NDP's focus from rural to urban concerns, so that the NDP gradually represented voters in cities and towns.
