Ms. Merkel's attempt to present herself as a Social Democrat was a clever move. But it's not working anymore. The divisions between the CDU and CSU have simply become too great for that.

Trump has a clear goal: the division of Europe and the destruction of the European domestic market. The fact that Brexit propagandist Nigel Farage was the first European he received in his tower speaks volumes. That is why we must strengthen the European domestic market and work even more closely together in Europe. That is absolutely compulsory for Germany.

Would I sacrifice a friendship to take a step forward in my political career? Thus far in my political career, I have been spared from having to make such a decision, thank God. And I can't imagine what it must be like.

The old fundamental principles must continue to apply, even in our changing society: Democracy knows neither master nor slave. Equal education opportunities for all, no matter where they come from and no matter who their parents are. Equal access as well when it comes to digitalization.

I am critical of the fact that Hungarian Prime Minister Viktor Orbán is pulling out of everything - the joint approach to the refugee issue, for example. He cannot disparage his colleagues in the EU either - that's not how we treat each other. We require solidarity: in refugee policies, just as in the financial architecture of the structural funds from which countries like Hungary have strongly profited from for years.

I really don't have time at the moment for coalition debates. The voters will decide what the next parliament will look like. Those who wish to form a coalition with The Social Democrats can take a look at our platform and then they are more than welcome to talk to us.

If cooperation among governments were the superior concept for progress in Europe, I'd be onboard immediately. But the problem is that cooperation isn't working.
