McDonough County is split between Illinois’ 15th Congressional District and Illinois' 17th Congressional District, with the majority of the county in the 15th. The Cities of Macomb and Bardolph are included in the 17th district, and the cities of Bushnell, Colchester, Prairie City, Good Hope, Sciota, Industry and Adair are in the 15th district. The 15th District is currently represented by Republican Mary Miller. The 17th District is currently represented by Democrat Eric Sorenson. For the Illinois House of Representatives, the county is yet again split between the 71st district and the 94th district. The Cities of Macomb, Bushnell, Bardolph, and Prairie City are represented by Republican Daniel Swanson of the 71st district. The cities of Colchester, Industry, Good Hope, Sciota, and Adair are currently represented by Republican Norine Hammond of the 94th district. The county is split along the same lines in the Illinois House as it is in the Illinois Senate, thus the 71st district of the house's lines are the same as the 36th district of the Illinois Senate. The 36th district of the Illinois Senate is represented by Democrat Michael Halpin. The 47th district of the Illinois Senate is represented by Republican Neil Anderson.

In presidential elections, McDonough County was once reliably Republican, voting for the Republican candidate in all but two elections (1912 & 1932) from 1892 to 1988. Since 1988, the county has become more competitive, with Democrats carrying the county three out of seven times and holding the Republican candidate's margin of victory to under four points three times. In 2020, however, McDonough County went for Trump by a margin of 16.5%.
