The coexistence of normality and variability is the characteristic of the three state elections in eastern Germany 2014. Due to the bonus as governing party，the largest party in these each federal states remains the same. But the political-party landscape in eastern Germany was reshuffled in the fierce competition of the old and the new political forces. The ongoing fragmentation of the party system，decline of the FDP and rise of the AfD led to growing uncertainty and unexpected innovation of coalition-building. The CDU becomes the dominating party with limited coalition possibility because of the loss of its traditional coalition partner，while the SPD is flexible in coalition-building on an overall unsatisfying level. With the approaching of the 25th anniversary of German reunification，the Left Party，deep rooted in eastern Germany as the follower-party of the former DDR，became increasingly integrated into the mainstream of the political culture through its historical transformation. The rise of right-wing populist partyAfD led to subsequent impacts on the German politics and brings new challenges to the mainstream political parties. <<
