Peer Steinbrück, who had been Minister-President for two and a half years by the time of the election, stood as lead candidate for the SPD. As in 2000, the CDU nominated state chairman Jürgen Rüttgers. Environment minister Bärbel Höhn led the Greens for a fourth time, and the FDP put forward Landtag group leader Ingo Wolf. The SPD and Greens aimed to continue their coalition, while the CDU and FDP sought to oust them with a coalition of their own. Polls showed the two blocs neck and neck at the start of the year, but the CDU and FDP established a strong lead by the start of March. Minister-President Peer Steinbrück remained popular and led Rüttgers in terms of personal polling; the SPD relied heavily on his personal image and placed less emphasis on the party brand, which was dragged down by federal issues The SPD also faced a challenge from the left in the form of
WASG, a party founded by trade unionists and disgruntled SPD members opposed to the federal government's
Agenda 2010. Important topics in the campaign were coal mining subsidies, wind energy, education, and the high unemployment rate. ==Opinion polling==
