Republicans Again Challenge Iowa Libertarian Candidates

Three Libertarian candidates seeking statewide and congressional office in Iowa may soon learn whether they will remain on the November ballot. Challenges filed by Republican activists, strategists, and voters seek to remove Libertarian gubernatorial candidate Nicholas Gluba and congressional candidates Rick Stewart and Marco Battaglia from the ballot, arguing they failed to comply with Iowa election requirements.

The challenges will be heard by a state panel on June 15.

The dispute has renewed a question that has surfaced repeatedly in Iowa politics. Are these efforts protecting the integrity of Iowa elections, or are they attempts to limit voter choice?

The Candidates Facing Challenges

The candidates facing objections are:

• • Nicholas Gluba, Libertarian candidate for governor
  • Rick Stewart, Libertarian candidate for Iowa’s 2nd Congressional District, and
  • Marco Battaglia, Libertarian candidate for Iowa’s 3rd Congressional District

Libertarian U.S. Senate candidate Thomas Laehn does not face a challenge and will appear on the November ballot.

Technical Defects or Meaningful Violations?

The challenges focus primarily on paperwork and filing issues. Gluba’s challenge alleges that his running mate was identified using a shortened version of her legal name and that his filing included an incomplete address.

Stewart’s challenge argues that some documents used the name “Rick Stewart” while others used “Richard Stewart.” Battaglia’s challenge alleges that he used his commonly known name rather than his legal name and may not have submitted enough valid signatures.

Republicans argue that election laws exist for a reason and should be applied consistently regardless of party affiliation. Libertarians counter that the challenges focus on technicalities rather than substantive problems and are designed to keep competitors off the ballot.

A Familiar Pattern

The dispute is not occurring in a vacuum. Conservative attorney Alan Ostergren successfully challenged several Libertarian congressional candidates in 2024, resulting in their removal from the ballot.

Two of the current candidates, Gluba and Battaglia, were among those affected and ultimately ran write-in campaigns after being removed from the ballot. This year’s challenges again target Libertarian candidates in competitive races.

Why It Matters

Republicans enter the 2026 election cycle facing several competitive contests. Political analysts have rated the governor’s race and multiple congressional races as highly competitive. And in close elections, even a small number of Libertarian votes could affect the outcome.

Historically, Libertarian candidates often draw support from voters who lean conservative on economic issues but are dissatisfied with Republican candidates or government policies. That reality has fueled skepticism among Libertarians who view the challenges as politically motivated.

Republicans reject that characterization and argue that candidates seeking public office have a responsibility to comply with election law.

The Bigger Question

The June 15 hearing may ultimately determine whether the challenged candidates remain on the ballot. But the broader debate extends beyond these three races. Should election officials strictly enforce every technical filing requirement, even when voters clearly understand who the candidate is? Or should ballot access be interpreted more broadly in favor of maximizing voter choice?

Reasonable people can disagree. What is clear is that the outcome will influence not only the candidates involved, but also how Iowans view the balance between election administration and voter access.

For Libertarians, the issue is straightforward. They argue elections should be decided by voters.

For Republicans filing the challenges, the issue is equally straightforward. They argue elections should be conducted according to the law.

The panel hearing the case will soon decide which argument carries greater weight.
