Robert Sweitzer

In 1910, Sweitzer was elected Cook County Clerk.[2] His election is largely acredited to the support he received from Democratic boss Roger Charles Sullivan.[2] Sweitzer would hold this position for the next 24 years.[2]

While serving as Cook County Clerk, Sweitzer was his party's nominee for Mayor of Chicago in 1915 and 1919, losing both consecutive elections to Republican William Hale Thompson. In 1915, Sweitzer had won the Democratic nomination after successfully challenging incumbent mayor Carter Harrison Jr., who was serving in his fifth non-consecutive term as mayor.[4][5] Sweitzer was a loyalist to Sullivan, who Harrison had been in a power struggle with throughout his fifth term as mayor.[4][5] In the Democratic primary, Sweitzer was able to build a coalition of ethnic groups that were put off by Harrison's war on crime.[6] Sweitzer also benefited from Harrison running a poor campaign.[5] Sweitzer defeated Harrison by a broad margin in the primary, but lost the general election to Thompson by an also broad margin. In 1919, Sweitzer, with Sullivan's backing, easily won the Democratic nomination, his only significant opponent being Tom Carey, former chair of the county committee.[7][8] He would lose the 1919 general election to Thompson by a close margin, with the election seeing four significant candidates (the other two being Maclay Hoyne and John Fitzpatrick).

In 1934, he was elected Cook County Treasurer. He assumed office on December 4, 1934.[2]

In Spring of 1935, Michael J. Flynn, his successor as Cook County Clerk, reported apparent discrepancies in the accounts of the office. An audit and subsequent disclosures revealed a deficit of $414,129 in the real estate tax redemption fund.[2] Shortly after this, the Cook County Board held a unanimous vote to remove Sweitzer from office and replace him with Joseph L. Gill, the Clerk of the Municipal Court.[2]

A grand jury indicted Sweitzer on charges of withholding $414,129 in public funds from his successor. However, he was acquitted after six hours of deliberation by the jury.[2] Sweitzer subsequently unsuccessfully attempted to get the courts to rule his removal from office as unconstitutional.[2]

After his acquittal, Sweitzer proclaimed that he would run for County Treasurer again, but he never did.[2]
