Donald Tusk, the former Prime Minister and former President of the European Council, has commented on the political stance of Roman Giertych, a prominent lawyer and politician. Tusk expressed his support for a particular idea proposed by Giertych, stating that it would create significant challenges for their political opponents.

In a post on his Twitter account (https://twitter.com/donaldtusk/status/1157236128199692288), Tusk wrote: "Mieliby z nim urwanie głowy. Szczególnie na Żoliborzu. Dużo nas różni, ale ten pomysł popieram." This translates to: "They would have their hands full with him. Especially in Żoliborz. Much divides us, but I support this idea."

The reference to "Żoliborz" is a clear allusion to Jarosław Kaczyński, the leader of the Law and Justice (PiS) party, whose political stronghold and residence are located in the Żoliborz district of Warsaw. Tusk's statement suggests that Giertych's actions or proposals would be particularly troublesome for Kaczyński and his party.

While Tusk acknowledged that he and Giertych have significant political differences ("Dużo nas różni"), he nonetheless endorsed Giertych's specific idea ("ale ten pomysł popieram"). The exact nature of the idea is not detailed in the provided text, but it is implied to be a strategy or action that would effectively challenge the current government.

This comment from Donald Tusk indicates a potential, albeit strategic and limited, alignment with Roman Giertych on certain political matters, aimed at confronting the ruling party in Poland.
