Although Nena said she disliked the English version of "99 Luftballons" because it was too "blatant" and that the Nena band was neither political nor a protest band, she has occasionally publicly lent her name in support of political causes. She supports "Ehe für alle" (marriage for everyone) and, as a mother of five, a campaign against the German government's plans to scale back the state provision of midwifery services. In March 2021 Nena expressed her support for the anti-COVID-19 lockdown demonstration in Kassel.
