The 2002 general election was characterised by changes in the political climate. The right-wing populist political commentator Pim Fortuyn entered into politics. He had an anti-establishment message, combined with a call for restrictions on immigration. Although his critique was oriented at the second Kok cabinet, Rosenmöller was one of the few politicians who could muster some resistance against his message. Days before the election, Fortuyn was assassinated. Ab Harrewijn, GroenLinks MP and candidate also died. Before and after the elections serious threats were made against Rosenmöller, his wife and his children. These events caused considerable stress for Rosenmöller. GroenLinks lost one seat in the election, although it had gained more votes than in the 1998 elections. Before the 2003 general election Rosenmöller left parliament, citing the ongoing threats against his life and those of his family as the main reason. He was replaced as chair of the parliamentary party and top candidate by Femke Halsema. She was unable to keep ten seats and lost two.
