The Hamburg elections of 29 February 2004, ended with an unprecedented landslide victory for Ole von Beust and the CDU, with the party achieving absolute majority in the city-state's parliament. The CDU gained 47.2 percent of the vote, a full 21-point increase from the previous election in September 2001. This was the first time since 1993 the city-state has had only a single ruling party. In the Hamburg elections of 24 February 2008, the CDU gained 42.6 percent of the vote. Thus, the CDU continued to be the strongest party in Hamburg. However, since the CDU lost its absolute majority, it formed a coalition government with the Greens.
