Why is "1937 United States Senate special election in Arkansas" trending?

Wikipedia Overview

The 1937 Arkansas special senatorial election was held on October 19, 1937, following the death of longtime Democratic senator Joe T. Robinson. Robinson was a powerful senator, staunch Democrat, and strong supporter of United States President Franklin D. Roosevelt, and was instrumental in passing many New Deal programs through the Senate. Arkansas was essentially a one-party state during the Solid South period; the Democratic Party controlled all aspects of state and local office. Recently elected Democratic Governor of Arkansas Carl E. Bailey initially considered appointing himself to finish Robinson's term, but later acceded to a nomination process by the Democratic Central Committee, avoiding a public primary but breaking a campaign process. Avoiding the primary so angered the public and establishment Democrats, leading them to coalesce behind longtime Democrat John E. Miller as an independent, forcing a general election.
