1926 Oklahoma gubernatorial election

James Brooks Ayres Robertson, sometimes called J. B. A. Robertson, was an American lawyer, judge and the fourth governor of Oklahoma. Robertson was appointed by the state's first governor, Charles N. Haskell, to serve as a district judge.

Henry Simpson Johnston was an American lawyer and politician who served as a delegate to the Oklahoma Constitutional Convention, the first president pro tempore of the Oklahoma Senate, and the seventh governor of Oklahoma. He would become the second governor in Oklahoma history to be impeached and removed from office.

The Oklahoma Senate is the upper house of the two houses of the Legislature of Oklahoma, the other being the Oklahoma House of Representatives. The total number of senators is set at 48 by the Oklahoma Constitution.

The President pro tempore of the Oklahoma Senate is the second-highest-ranking official of the Oklahoma Senate and the highest-ranking state senator. The Oklahoma Constitution designates the Lieutenant Governor of Oklahoma as the highest-ranking official, serving ex officio as President of the Senate, even though the lieutenant governor only votes in the case of a tie. During the lieutenant governor's absence, the president pro tempore presides over sessions. By longstanding custom, the lieutenant governor presides over sessions devoted to ceremonial purposes, while the bulk of the legislative management and political power is reserved for the president pro tempore, who is elected directly by the Oklahoma Senate.

The Democratic Party is one of two major contemporary political parties in the United States. Founded in 1828, it was predominantly built by Martin Van Buren, who assembled politicians in every state behind war hero Andrew Jackson, making it the world's oldest active political party. Its main political rival has been the Republican Party since the 1850s, with both parties being big tents of competing and often opposing viewpoints. Modern American liberalism — a variant of social liberalism — is the party's majority ideology. The party also has notable centrist, social democratic, and left-libertarian factions.

The Republican Party, also referred to as the GOP, is one of the two major contemporary political parties in the United States. The GOP was founded in 1854 by anti-slavery activists who opposed the Kansas–Nebraska Act, which allowed for the potential expansion of chattel slavery into the western territories. It has been the main political rival of the Democratic Party since the mid-1850s. Like them, the Republican Party is a big tent of competing and often opposing ideologies. Presently, the Republican Party contains prominent conservative, centrist, populist, and right-libertarian factions.

The first modern Farmer–Labor Party in the United States emerged in Minnesota in 1918. Economic dislocation caused by American entry into World War I put agricultural prices and workers' wages into imbalance with rapidly escalating retail prices during the war years, and farmers and workers sought to make common cause in the political sphere to redress their grievances.

The Socialist Party of America (SPA) was a socialist political party in the United States formed in 1901 by a merger between the three-year-old Social Democratic Party of America and disaffected elements of the Socialist Labor Party of America who had split from the main organization in 1899.
