Editing Political realignment (section)

===Alberta===
Alberta has had a tradition of [[Dominant-party system|one-party dominance]], where a party forms government for an extended period before losing power. From 1905 to 2015, Alberta only changed governments (often called "dynasties") four times, with no party ever returning to government. The elections of [[1921 Alberta general election|1921]], [[1935 Alberta general election|1935]], [[1971 Alberta general election|1971]] and [[2015 Alberta general election|2015]] each marked the end of a particular dynasty and a realignment of the province's party system.<ref>{{Cite news |date=May 5, 2015 |title=The PC dynasty falls: Understanding Alberta's history of one-party rule |language=en-CA |work=The Globe and Mail |url=https://www.theglobeandmail.com/news/alberta/albertas-political-dynasties/article24255480/ |access-date=May 25, 2022}}</ref>

The [[2019 Alberta general election|2019 election]] has also been suggested as a realignment: although the [[Alberta New Democratic Party|New Democratic Party]] was defeated after only one term, they retained a strong base of seats and remained competitive in opinion polling and fundraising, pointing to a possible development of a competitive [[two-party system]] against the [[United Conservative Party]].<ref>{{Cite journal |last=Bratt |first=Duane Thomas |date=2022 |title=Alberta's Transition to a Two-Party System: The 2015 and 2019 Elections |url=https://ojs.unbc.ca/index.php/cpsr/article/view/1838/1411 |journal=Canadian Political Science Review |volume=16|pages=32–41 |doi=10.24124/c677/20221838 }}</ref>
