Elections to the European Parliament
In 2004, Harms was the top candidate of the Alliance 90/The Greens for the Elections to the European Parliament and in 2009 she was elected again for parliament. Ahead of the 2014 elections, she lost out against fellow German MEP Ska Keller to lead the European Greens’ campaign alongside José Bové; however, she eventually led the German Green Party in the election campaign.
