A Milwaukee man who pleaded guilty last month to voting twice in the 2012 presidential election will begin serving a six-month sentence on Monday, according to The Milwaukee Journal Sentinel.

Chad Gigowski, 28, told a judge on Thursday that he was “truly sorry” for his actions, and that he had not been part of any organized voter fraud effort, but rather under the influence of alcohol and drugs, when he double voted last year.

According to the Journal Sentinel, Gigowski used an old driver’s license to vote in Greenfield, Wis. on election day, signing a form stating he was a Greenfield resident. Later in the day, Gigowski used a Department of Workforce Development letter, addressed to him at a Milwaukee address, to register and vote in Milwaukee. He also signed a form stating that he had not previously voted in the election.

In exchange for his guilty plea, prosecutors dropped two other counts, fraudulent registration and registering in more than one place. But while Assistant District Attorney Bruce Landgraf recommended a nine-month sentence, Gigowski’s attorney had argued that no prison time was necessary. Gigowski’s sentence includes work-release privileges. He will also be on probation for 2 1/2 years.
