Historically, the district has had a strong Republican lean. It occasionally elected Democrats in the past, but the Democrats have not come close to winning it since 1994. Pockets of Democratic influence exist in Fort Wayne itself, which frequently elects Democratic mayors and occasionally sends Democrats to the state legislature. However, it is nowhere near enough to overcome the overwhelming Republican trend in the rest of the district.
5 Blackford County exists in both the 3rd and 5th Congressional districts. One city, Montpelier, exists in the 3rd congressional district, and one city, Hartford City, exists in the 5th congressional district. One township, Harrison, exists in the 3rd congressional district, and three townships, Washington, Licking, Jackson, exist in the 5th congressional district.
