A special election was held on April 28th, 2017 in Illinois' 4th congressional district, due to Representative Luis Gutiérrez being elected Vice President of the United States.
The district was featured by The Economist as one of the most strangely drawn and gerrymandered congressional districts in the country and has been nicknamed "earmuffs" due to its shape. It was created after federal courts ordered the creation of a majority-Hispanic district in the Chicago area. The Illinois General Assembly responded by packing two majority Hispanic parts of Chicago into a single district.
Cook County Commissioner Jesús "Chuy" García, who had previously been considered a prospective 2019 Chicago Mayoral candidate, succeeded Gutiérrez, winning 87% of the general election vote.
