The bill establishes a requirement for runoff elections for specific offices, including governor, secretary of state, and federal positions, if no candidate secures a majority of votes in the primary elections. The runoff will feature the top two candidates from the primary, with provisions for ties and withdrawals. Runoff elections are scheduled for the first Tuesday after the second Monday in August during general election years. To manage the costs associated with these elections, a runoff election account will be created and overseen by the secretary of state. The bill also amends various sections of the Election Code, changing the primary election date to the first Tuesday after the first Monday in May and updating voter registration and absentee voting procedures.

In addition to the runoff provisions, the bill modifies the timeline for county commissioners to divide election districts, moving the deadline from the first meeting in May to the third Tuesday in January of general election years. It also adjusts deadlines for notifying county chairmen about election officials, changing the notification date from the third Tuesday in April to the first Tuesday in February. The bill includes new guidelines for electioneering communications and prohibits the use of political party funds to favor one candidate over another in primary or runoff elections. Furthermore, it mandates a review by the joint corporations, elections, and political subdivisions interim committee to evaluate the adequacy of current election dates for candidate registration following legislative redistricting, with an appropriation of $2 million from the general fund to support runoff elections.
