2002 Illinois elections
Elections were held in Illinois on Tuesday, November 5, 2002. Primary elections were held on March 19, 2002.
The Democratic Party made gains in these elections, while the Republican Party conversely saw losses. The Democratic Party retained their control of the State House and flipped control of the State Senate. The Democratic Party also won the Governorship and Lieutenant Governorship in their combined election, ending 26 years of Republican control of the state's executive branch. In addition, among the other four statewide elected offices, the Democratic Party retained their hold of two, while flipping another. This left Illinois Treasurer Judy Baar Topinka as the sole remaining Republican holder of a statewide office.
The losses for Republicans continued a decline of fortunes that had taken place in the state of Illinois over the last several elections for the party, which previously had held all statewide elected offices and both chambers of the Illinois General Assembly in the mid-1990s.
