On February 25, 1925, as he was preparing to leave office, McCormick died in what is considered to have been a suicide (though the suicidal nature of his death was not known to the public, contemporarily). His reelection loss is believed to have contributed to his suicide. McCormick's widow Ruth Hanna McCormick would go on to defeat Deneen in the 1930 Republican primary. ==See also==
