Campaign Partisan dynamics Lewis was considered a formidable candidate, and campaigned with vigor. As a result of McCormick's wavering on the issue of prohibition, the
Anti-Saloon League ultimately endorsed independent candidate Lottie Holman O'Neill over McCormick.
Gender and sexism Lewis made a point not to refer to McCormick by name, instead calling her "the lady candidate". McCormick refused to make her gender an issue, calling gender differences a personality issue and insisting political party mattered more in the general election. Thompson went as far as to, on October 23, 1930, print and distribute a pamphlet which accused McCormick's late husband of having made
racist remarks, an attack that McCormick called, "malicious and unjustifiable".
Great Depression While neither McCormick nor Lewis treated the economic turmoil as a main issue, until the closing days of the campaign, it was ultimately a deciding factor in the election. Chicago was particularly hard-hit at the time by the
Great Depression. While she did not originally treat it as the central issue of the campaign, by the end, McCormick admitted that, in the election, rather than prohibition, voters were more focused on the economy, saying, "the question is not whether everybody gets a bottle of beer, but whether everybody gets a job". She argued that Democratic rule would worsen the economic turmoil.
Results J. Hamilton Lewis won by a broad margin, becoming the first Democrat to be popularly elected to the United States Senate from Illinois. McCormick was the first Republican to lose a popular U.S. senate election in Illinois. ==Aftermath==
