Upon its admission to the Union in 1912, the state was dominated by Democrats who had migrated there from the South, and aside from the landslide victories of Republicans Warren Harding, Calvin Coolidge and Herbert Hoover, the state voted for Democrats until 1952, when Dwight Eisenhower carried it, and began a lengthy streak of GOP victories interrupted only by Bill Clinton 's narrow victory in 1996. Since then, the state has remained in the GOP camp, although Donald Trump won it by only 3.5 % in 2016. Incumbent Republican Senator Jeff Flake announced in October 2017 that he would retire at the end of his current term instead of seeking reelection for another term in 2018. Flake had said in March 2017 that he was running for reelection, but was considered vulnerable due to low approval ratings, a tenuous relationship with President Trump, and a primary challenge from former State Senator Kelli Ward.
