## Politics

From 1994 until 2018, the district was represented by Republicans. The district was considered to be a Republican stronghold during this time. 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 commissioner of the district flipped to the Democratic Party in 2018, a year which saw an overall strong performance by the Democratic Party in that year's elections in Illinois and an unprecedentedly strong and well-funded effort by the Cook County Democratic Party to target the district.
