Abwählen = recall?

If I understood correctly: it is possible to recall senators in Wisconsin before the end of their term by public vote. When you look at an election poster for next Sunday's state elections in Baden-Württemberg, you read the words: Jetzt abwählen (recall now), and you wonder. 

You can vote alright, but how to recall the Christian Democrats (Conservatives or black) + the Free Democrats (Liberals or yellow)?

What actually is meant is do not vote in Sunday's election for nuclear power. The issue is represented by the present coalition government of black and yellow here in the Ländle, but since Fukushima loaded with German Angst. 

While it is impossible to recall deputies in Germany, it is possible to refrain from voting for them in the upcoming election.
