The Chicago mayoral election of 1943 was held on April 6, 1943. The election saw incumbent Edward J. Kelly being reelected to a third term, defeating Republican nominee George McKibbin with a 9% margin of victory. Both nominees had received landslide victories in their party's primary elections.
The election was preceded by primary elections held on February 22, 1943 to determine the nominees of both the Democratic Party and the Republican Party.
Reform-oriented Democrats supported a challenge by alderman John S. Boyle to incumbent mayor Edward J. Kelly.[1] This challenge failed to amount to much, with Kelly easily defeating Boyle.
George McKibbin won the Republican nomination by a landslide margin.
Like other Republicans that had run against Kelly, McKibbin framed his campaign as a crusade against machine politics.[1] McKibbin declared "Pendergast is out in K.C., Hague in Jersey, and Tammany in New York have been cleaned out. Now it is time to clean out the Kelly-Nash machine."[1] McKibbin also attacked links between the political machine and criminal activity.[1] Kelly did not campaign. Confident in his chances of victory, Kelly flaunted heavy gravitas and balked at the thought of campaigning.[1]
Voter turnout was considered to be very light.[1] Kelly won what was considered to be a very solid victory.[1]
