Until January 1, 2006, Kentucky did not track party affiliation for registered voters who were neither Democratic nor Republican.[6] 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.[7]
