Bagatsing succeeded her father
Amado Bagatsing in his congressional seat at
Manila's 5th congressional district in
2016, after winning in a six-way race (with one of them is former congressman
Joey Hizon). Her candidacy was motivated by a signature campaign from constituents advocating for a successor to continue her father's initiatives, as she had assisted her father with youth-oriented programs and projects. She was also a member of the
House Committee for Women and Gender Equality and is a co-author of the
SOGIE Equality Bill. She ran for 2nd term in
2019 under KABAKA and
PDP–Laban and won, defeating councilor
Ali Atienza. She ran for 3rd term in
2022 under KABAKA and
National Unity Party, but lost to councilor
Irwin Tieng of
Asenso Manileño by an estimate of 3,000 votes. In 2025, she was appointed
officer in charge of the Department of Tourism, Culture, and Arts of
Manila under the second administration of Mayor
Isko Moreno. == Electoral performance ==
