"A group like this"?? This is the CDU, which has been the main political party since the war, in power from 1949 to 1969 and from 1982 to 1997. There's nothing amazing about their coming back into power at all. The party will almost certainly win, but don't expect anything too radically different from the current government in the foreign policy sphere: Angela has already ruled out for Germany a military option in Iran.
The changes will be even less marked if the election results only permit a "Grand Coalition" with the SPD (Socialists). This happened in 1966-69.
Just FYI.
From left to right (top): Peter Müller (economy and labour), Paul Kirchhof (finances), Ursula von der Leyen (social issues, health system, families), Annette Schavan (education and research), continued (bottom): Gerda Hasselfeldt (farming and environment), Günther Beckstein (interior and national security), Norbert Lammert (culture) und Wolfgang Schäuble (foreign affairs and defense).The CDU in general is a whole lot more liberal than this, I'm talking about Merkel and her allies specifically.
