For five years, North Rhine-Westphalia has been governed by a conservative: Jürgen Rüttgers. He cultivates a socially-responsible, fatherly image and wants to continue as the state’s leader in a coalition with the free-market, liberal FDP after May 9.That will not be easy in what is traditionally a Social Democrat bastion and former industrial region going through transformation. Rüttgers knows if he loses, it will also be a defeat for the conservative-free market coalition on the federal level in Berlin, because it would lose its majority in the Bundesrat, the house of parliament that represents the states.
