The district's character is very different from the rest of Kentucky. It is entirely contained within Jefferson County, and in contrast to the rest of the state, it is urban and leans Democratic. It has the highest percentage of African Americans in the state, who are concentrated in and near Louisville. It is a cosmopolitan, diverse district, with major businesses, health care organizations and universities.
Until January 1, 2006, Kentucky did not track party affiliation for registered voters who were neither Democratic nor Republican.[5] The Kentucky voter registration card does not explicitly list anything other than Democratic Party, Republican Party, or Other, with the "Other" option having a blank line and no instructions on how to register as something else.[6]
