The inauguration of the 102nd General Assembly occurred on Wednesday January 13, 2021.[2]
The elections for United States President, Illinois United States Senator, Illinois's 18 congressional districts, the Illinois Fair Tax and the Illinois House were held on this date.
The Republican Party needed to gain 11 seats to earn a majority in the Senate. The Democratic Party gained one seat towards their already-existing supermajority.
