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 candidate withdrawals. Runoff elections are scheduled for the first Tuesday after the second Monday in August during general election years. Additionally, the bill creates a runoff election account to manage associated costs, overseen by the secretary of state. It also amends various sections of the Election Code to clarify primary election timing, voter registration requirements, and candidate certification, including changing the primary election date to the first Tuesday after the first Monday in May.

Further amendments include specifying that runoff elections must be indicated on political party ballots and adjusting the timeline for county commissioners to divide election districts to the third Tuesday in January of general election years. The bill modifies deadlines for notifying county chairmen about election officials, updates compensation schedules for election judges, and revises the timeline for the county canvassing board's meetings. It also mandates the publication of election proclamations within specific timeframes and requires a review by the joint corporations, elections, and political subdivisions interim committee to ensure adequate candidate registration time post-redistricting. The bill appropriates $2 million from the general fund to support runoff elections and outlines effective dates for its provisions, with some taking effect immediately and others on July 1, 2025.
