Calgary is generally considered a conservative city, dominated by traditional small-c social conservatives and fiscal conservatives. As the city is a corporate power-centre, a high percentage of the workforce is employed in white-collar jobs. The high concentration of oil and gas corporation led to the rise of Peter Lougheed's Progressive Conservative Party in 1971. During the 1990s the city's mainstream political culture was dominated by the right-wing Reform Party of Canada federally, and the Progressive Conservatives provincially.
The Green Party of Canada has also made inroads in Calgary, exemplified by results of the 2004 federal election where they achieved 7.5% of the vote across the city and 11.3% in the Calgary North Centre riding. The right-wing Alberta Alliance became active during the 26th Alberta general election and campaigned for fiscally and socially conservative reforms. However, the Alberta Alliance and its successor, the Wildrose Alliance, did not manage to make inroads in the 2008 provincial election.
However, as Calgary's population has increased, so has the diversity of its politics. One growing alternative movement was recently active during the 2000 World Petroleum Congress demonstrations and the J26 G8 2002 protests. Protesters were a mix of locals and outsiders. The city has chapters of various activist organizations, as well as an Anti-Capitalist Convergence.
