Here’s what happened.

Pope Leo XIV has made American political history, becoming the first sitting pope known to cast a ballot in a United States election.

The Vatican confirmed Friday that the American-born pontiff submitted a mail-in ballot in Illinois ahead of the November 3, 2026, midterm elections, marking an unprecedented moment in the history of the Catholic Church.

The announcement comes as Republicans and Democrats prepare for a consequential election that will determine control of Congress and influence the remainder of President Donald Trump’s second term.

While the pope’s political choices remain private, his decision to participate in the election has drawn attention to the historic connection between the Vatican and American democracy.

Vatican Confirms Pope Leo Cast His Ballot

The Holy See Press Office confirmed on October 30 that Pope Leo XIV had exercised his voting rights as an American citizen.

Born Robert Francis Prevost in Chicago, Illinois, Leo became the first American-born pope when he was elected to lead the Catholic Church in May 2025.

Despite assuming one of the world’s most prominent religious positions, he has maintained his American citizenship and remains eligible to participate in U.S. elections.

According to Vatican officials, voting has been a longstanding practice for the pontiff.

The Holy See explained that Leo participated in elections whenever he was legally eligible, including during the years he lived and worked in Peru.

The Vatican also emphasized the pope’s belief that citizens have both the right and responsibility to participate in the democratic process.

His decision makes him the first known sitting pope to vote in an American election, adding another historic distinction to an already remarkable papacy.

Illinois Election Officials Reveal Details

The development first gained attention when election officials in Illinois confirmed that Robert Francis Prevost had requested a mail-in ballot for the upcoming midterm elections.

According to reporting from the Chicago Sun-Times, the Will County clerk’s office received the request on October 3.

Kim Fladhammer, the clerk’s office chief of staff, confirmed that Prevost appeared among registered voters requesting mail-in ballots.

The Vatican subsequently verified that the pope had submitted his completed ballot in Chicago.

Under Illinois election law, registered voters may cast ballots by mail without providing a special justification.

Federal voting protections also allow eligible American citizens residing overseas to participate in federal elections.

Those provisions make it possible for Pope Leo to exercise his voting rights while carrying out his responsibilities in Vatican City.

Importantly, neither the Vatican nor Illinois election officials disclosed which candidates received his support.

Pope’s Vote Comes During Major Midterm Battle

The historic announcement arrives at a critical moment in American politics.

Republicans are fighting to maintain control of Congress, while Democrats are working to regain power in Washington.

All 435 seats in the U.S. House of Representatives are on the ballot this November, along with 35 Senate seats.

The results will help determine whether President Trump can advance his legislative priorities during the final two years of his second term or face stronger opposition from congressional Democrats.

Several issues have dominated the national political debate, including inflation, immigration, government spending, national security and the direction of the American economy.

For voters concerned about the country’s future, the midterm elections represent an opportunity to influence decisions that could affect their families, communities and financial security.

Although President Trump himself is not on the ballot, the outcome could significantly affect his administration’s ability to pursue its agenda.

Illinois Governor’s Race Draws Attention

The pope’s home state is also holding an important gubernatorial election.

Democratic Gov. J.B. Pritzker is seeking a third term against Republican Darren Bailey and independent candidate Collin Corbett.

The contest gives Illinois voters a choice over the future direction of state government, including economic policies, taxation and public spending.

Pritzker has been a prominent Democratic critic of the Trump administration, while Bailey has campaigned as a conservative alternative.

However, there is no public evidence indicating which candidate Pope Leo supported.

The Vatican’s announcement focused on his participation as a citizen rather than his preferences in any particular political contest.

That distinction is important because the pope’s decision to vote should not be interpreted as a public endorsement of either major political party.

Historic First For An American-Born Pope

Pope Leo’s participation carries special significance because he is the first pontiff born in the United States.

Before his election as pope, Robert Prevost spent much of his religious career serving communities in Peru, eventually becoming a bishop and taking on senior responsibilities within the Catholic Church.

His election to the papacy in 2025 was a milestone for American Catholics and the global Church.

Now, his decision to cast a ballot in the 2026 midterms represents another unusual chapter in papal history.

Popes traditionally avoid endorsing individual candidates in American elections, even when addressing moral and social questions that intersect with political debates.

Leo has publicly discussed issues such as immigration, the protection of human life and the responsibilities of government.

Nevertheless, his personal vote remains private, and the Vatican has not attempted to portray his participation as a political endorsement.

Why Pope Leo’s Decision Matters

Beyond the historic nature of the announcement, the pope’s decision highlights a longstanding principle of American democracy: eligible citizens have the opportunity to participate in choosing their elected representatives.

For Americans who have spent decades following elections, the development offers an unusual example of civic participation reaching even the highest levels of international religious leadership.

The pope’s position as leader of the Catholic Church does not erase his American citizenship or automatically prevent him from exercising his legal voting rights.

His participation also demonstrates how Americans living abroad can remain involved in elections at home.

With millions of voters preparing to make their choices, the Vatican’s announcement adds a distinctive international dimension to the 2026 midterms.

Election Day Approaches With Control Of Congress At Stake

Americans will head to the polls on Tuesday, November 3, with the direction of the federal government hanging in the balance.

The results will determine the composition of the next Congress and shape political battles over federal spending, border security, taxes and other major issues.

Republican victories would strengthen the party’s ability to work with President Trump, while Democratic gains could create additional obstacles for the White House.

Meanwhile, the historic participation of Pope Leo XIV serves as a reminder that American elections can involve citizens far beyond the nation’s borders.

For the first time in history, the leader of the Roman Catholic Church is among those known to have cast a ballot in a U.S. election while serving as pope.

Although Americans may never know which candidates received his vote, one fact is now established: Pope Leo XIV has made election history.
