When considering Jesus “Chuy” Garcia’s impressive run to become Chicago’s next mayor, many cannot help but make historical comparisons. Understandably, Harold Washington’s historic victory in 1983 springs to mind—not the least because Garcia served as a key Washington ally during those years.

Cermak—yes, there’s a street, formerly 22nd, named after him—pulled off an incredible victory by defeating William “Big Bill” Thompson. The parallels to the current election are striking.

Cermak arrived in the United States as an infant with his Czech parents from the Austro-Hungarian Empire. Like most immigrants, they came with next to nothing. First, they lived in a small town south of Joliet where Cermak, just a child, worked with his father in a coalmine. When Cermak was 12, his family moved to Chicago’s South Lawndale neighborhood, home to a large and thriving Czech community—the same neighborhood Garcia lives in today, more commonly referred to as Little Village and the heart of the city’s Mexican population.

As a teen, Cermak worked as a railroad brakeman and teamster, earning the nickname “Pushcart Tony,” before entering politics. He was elected to the state House of Representatives, City Council and Cook County Board of Commissioners before announcing his intention to become mayor. Incredibly, Garcia also was elected to the state legislature, City Council and County Board. ...
