The Pope fulfilled his "civic duty". The Vatican issued a statement

Pope Leo XIV participated in the U.S. midterm elections, voting by mail in Chicago, his hometown. The Vatican confirmed his civic engagement, stating he has always exercised his voting rights when eligible. The Pope also voted while living in Peru, where he spent over 20 years and holds citizenship. Midterm elections involve voting for all House representatives, 35 senators, and governors in 36 states, with voting day on November 3, although many have already voted by mail.
