Voters in Downington, Pennsylvania elected Erica Deuso as mayor on Tuesday night, making her the first out transgender mayor in state history amid a night of major wins for pro-LGBTQ+ Democrats across the country.

Deuso, who works in management at the pharmaceutical company Johnson & Johnson, defeated Republican Rich Bryant with 64% of the vote, the Philadelphia Inquirer reported. As mayor, Deuso will oversee the Philadelphia suburb’s police department and cast tie-breaking votes on the policymaking Borough Council.

“Being elected as Pennsylvania’s first openly transgender mayor is deeply meaningful, and I carry that responsibility with pride and humility,” Deuso wrote in a Facebook post on Wednesday morning. Her victory made her the fourth known trans person to become mayor of a U.S. city. “I hope it reminds anyone who has ever felt unseen, unheard, or underestimated that your voice matters, and that you belong in the room where decisions are made.”

In a statement obtained by WHYY, Bryant said he extended “sincere congratulations to my opponent and wish them wisdom and success in leading our borough forward.”

Deuso — who is also bisexual — is a member of the Chester County Democratic Committee and the treasurer of the Pennsylvania Equality Project, a statewide LGBTQ+ advocacy nonprofit. Her campaign largely did not focus on LGBTQ+ issues, however, instead prioritizing infrastructure development and a plan for “environmental resilience” (a similar tactic to the 2017 campaign of Danica Roem in Virginia, who rode to office on a platform of fixing highway infrastructure). She has also pledged that under her leadership, local police would not cooperate with federal immigration agents “except for where legally obligated.”
