The Brandenburg state election, 2004, was conducted on 19 September 2004, to elect members to the Landtag of Brandenburg, the state legislature of Brandenburg.
Before Brandenburg, the SPD had lost many state elections, what was connected to Gerhard Schröder's Agenda 2010 policy, which was a reaction to the problems of constantly high unemployment in Germany. The establishing of a lower welfare payment (called Hartz IV after an expert who had invented it) for people unemployed for more than a year had driven many voters to the left Party of Democratic Socialism (PDS) party in the east, to the new-founded WASG in the west or away from the elections at all. Since 2003 the CDU had won more and more states, whereas the SPD suffered a string of heavy defeats.
In Brandenburg, both minister-president Matthias Platzeck (SPD) and his partner Jörg Schönbohm (CDU) supported the labour reforms. Against this campaigned the PDS and the far-right German People's Union (DVU), which had gained seats in the Landtag in 1999 for the first time.
Despite predictions that the PDS could become strongest party in an election for the first time, the SPD managed to remain in front, but dropped significantly. The CDU also lost votes and fell into third place.
Matthias Platzeck (SPD) remained Minister-President and continued the previous SPD-CDU coalition.
