Politics
The district has only had Republican commissioners since its inception, the only district for which this is the case. The district has been considered solidly Republican. Nevertheless, it saw a close result in its most recent election, which saw an unprecedentedly strong and well-funded effort by the Cook County Democratic Party to target the district.

For decades after its inception, the district was considered to be a Republican stronghold. However, in the 2016 United States presidential election, the Democratic ticket of Hillary Clinton and Tim Kaine won a strong victory in the district over the Republican ticket of Donald Trump and Mike Pence.

The district is currently the district represented by a Republican commissioner, and the only one to never have been represented by the Democratic commissioner.
