Illinois is a significant state in USA politics, as a microcosm of the country, meaning its demographics reflect those of the entire country. Additionally several US presidents have ties to the state, and three presidents were elected while living in Illinois: Abraham Lincoln, Ulysses S. Grant, and Barack Obama. Illinois pays tribute to its connection to Lincoln with its nickname, Land of Lincoln, and the Lincoln Presidential Library and Museum in the capital.
