Arizona
Arizona joined the Union in February 1912 as the 48th state and final piece of the continental United States. The state has traditionally gone Republican in presidential elections. Except for Bill Clinton’s win in 1996, Arizona voted Republican from 1952 through 2016. However, that 2016 election saw Donald Trump win by a narrower margin than other recent GOP nominees and in 2020 Joe Biden won the state by 0.3%. Biden's 49.4% support was the highest level for a Democratic candidate since 1964.
The Grand Canyon State’s population has grown rapidly in the past half century, and its number of electoral votes has almost tripled from four in 1960. In a bit of a surprise, the state did not gain an additional electoral vote after the 2020 Census.
