In the 2021 German Federal Election, Ganserer was elected to the Bundestag on the Alliance 90/The Greens list for Bavaria. However, because Ganserer has not changed her legal name in protest against the German Transsexual Act, which requires invasive psychological evaluations to change name and gender marker, she was forced to appear on the ballot under her deadname. Along with fellow Green Nyke Slawik, Ganserer became the first openly transgender person elected to the German Parliament.
