Costs for Replacing Voting Equipment in 2024, a joint analysis from the Brennan Center and Verified Voting

Between 2014 and 2022, the Brennan Center and Verified Voting released a series of analyses detailing the problem of aging voting equipment in the United States. These analyses rely on data provided by Verified Voting, which has been tracking voting equipment usage since 2006. This update examines the state of the nation’s voting systems ahead of the November 2024 elections.

When we first reviewed the status of voting equipment nearly a decade ago, we found that almost a quarter of all Election Day voters in 2016 would cast their votes on machines that did not produce a paper backup of their vote. Election experts consider a paper backup to be a critical security measure to ensure that ballots are counted as the voter intended. By 2024, that number has dropped dramatically, with only three states likely to still use paperless voting equipment in 2024. Indeed, we estimate that in the upcoming presidential election, nearly 99 percent of all registered voters will live in jurisdictions where they can cast a ballot with a paper record of the vote, including 100 percent of voters who will cast ballots in battleground states.

Much of the progress that has been made since 2016 is due to an influx of federal funds for election security. In 2017, in the wake of unprecedented cyber threats to elections, the Department of Homeland Security designated election equipment as critical infrastructure. After this designation, Congress provided $380 million in 2018 to help states acquire secure election technology, followed by another $425 million in 2020. Since the 2020 election, Congress has continued to provide election security grants, but in far lower amounts — just $75 million in both 2022 and 2023. This federal funding is the first of its kind since 2010 and helped make it possible for many states to replace outdated equipment.

But upgrading voting technology is a continuous process. Like any type of electronic equipment, voting machines age and need to be upgraded, and continued funding for elections makes this possible.

Small technical failures with voting equipment can lead to viral misinformation about the trustworthiness in elections. While minor errors and disruptions in elections do sometimes occur, election officials have numerous checks and processes in place to help make sure any issues are caught and addressed. And federal and state authorities should do all they can to support election officials in minimizing such errors. Election administration itself has been under a microscope in recent years, with domestic and foreign actors looking to exploit any problem for the purpose of undermining confidence in the entire democratic system. Jurisdictions can reduce the likelihood of disruptions on Election Day by replacing their outdated equipment.

There are other reasons jurisdictions will want to purchase new voting equipment in the next few years. Most importantly, the independent and bipartisan Election Assistance Commission recently approved the most significant update to federal voting technology standards since 2005. These standards, called the Voluntary Voting System Guidelines, set baseline requirements for voting machine cybersecurity, accessibility, and usability that vendors agree to meet, and that most states require for any voting machine in use. Adherence can help election officials assure voters that their technology has been certified by independent and authoritative standards and can reassure a public that is increasingly exposed to false conspiracy theories about the security of our nation’s voting equipment.

There are several categories of machines that ought to be replaced.

Direct recording electronic voting machines

Direct recording electronic voting machines use push buttons, dials, or touchscreens to record votes. This equipment has faced criticism from security experts because it records votes directly into computer memory and, in the case of some equipment, lacks voter-verified paper audit trail printers.

Significant progress has been made in recent years toward phasing out the direct recording electronic voting machines. In 2016, 22.4 percent of registered voters lived in jurisdictions using those direct recording machines that did not produce a paper backup. This year, we anticipate this figure to be closer to 1.4 percent.1

Our 2022 analysis found that six states still used paperless equipment. By November, many of those machines will be replaced. Indiana, Mississippi, and Tennessee have all passed legislation that requires localities to update or replace their paperless machines with systems that produce a paper record of every vote. An Indiana bill requires all counties using direct recording electronic voting machines to be equipped with voter-verified paper audit trail printers by 2024. In 2022, Mississippi passed legislation requiring the use of voting systems that produce voter-verifiable paper ballots starting in 2024; that same year, a Tennessee law required all direct recording electronic voting machines used in the state to be equipped with voter-verified paper audit trail printers by 2024. Kentucky has also replaced its remaining DREs.

Texas counties have until 2026 to replace their paperless direct recording electronic voting machines, though several counties have already made progress toward this goal. Louisiana, which has used paperless direct recording electronic voting machines statewide since 2006, intends to replace its voting machines with a paper-based system; however, this may not take place before the November 2024 presidential election.

The number of states with jurisdictions using the direct recording machines with voter-verified paper audit trail printers has decreased as well. The Brennan Center’s first analysis in 2014 found that jurisdictions in 22 states used some form of the direct recording machines as the primary polling place equipment. Ten years later, that number has shrunk to eight.

Machines that are reaching the end of their life cycle

Just like phones and computers, voting machines become obsolete with age. Twenty-first century electronic voting machines are considered to have a lifespan of 10 to 20 years, with most systems leaning closer to 10. Election officials often have difficulty finding machines that can run on outdated software, and, according to cybersecurity expert Jeremy Epstein, “From a security perspective, old software is riskier, because new methods of attack are constantly being developed, and older software is likely to be vulnerable.”

In November 2024, we expect that nearly 44.6 million registered voters will live in jurisdictions using principal voting equipment that was first fielded more than 10 years ago.2 This number has slightly increased since 2022 because states and territories that replaced their voting equipment as recently as 2014 are now using equipment that may be at or beyond its lifespan. We expect these to be among the first states to want to purchase new equipment that complies with the new federal voting system guidelines.

Voting machines may also pose issues for election officials if the equipment is discontinued. Replacement parts and technicians become difficult to find for equipment that is no longer being manufactured. One election official expressed that he felt “lucky to be able to get spare parts” for discontinued systems in his jurisdiction. In November 2024, about 10 million registered voters will live in jurisdictions using principal voting equipment that is no longer manufactured. This number has decreased dramatically from 21 million registered voters in 2022.
