When Tusk completes his seocnd term then all hell will break loose between him, Schetyna, Budka and Kopacz
Not really. That issue has been and gone, as Tusk will no longer have any ambitions of being PM. Kopacz had her chance, and she will be loyal to Schetyna now. Schetyna will naturally back Tusk for the Presidency as the most obvious and successful candidate, so PO are actually in quite good shape now. Is it enough to win the 2019 election? No, not yet. Much more hard work needs to be done between now and then.
Now, what about the latest developments within PiS? I've just read this article - natemat.pl/206137,zaczela-sie-gra-na-rozlam-kontra-najbrutalniejszy-atak-tak-w-wielka-sobote-rozpetala-sie-wielka-wojna-na-prawicy - what's your thoughts, Polly?
My own opinion is that Macierewicz should go. He's shown terrible judgement and lied through his teeth on several occasions, and PiS don't need him. Poland needs a Defence Minister who will concentrate on building up military cooperation with both Europe and America - Jarek has always said that a common European defence force is in Poland's interests (which it is), and getting more American troops on the ground won't hurt any as well. Macierewicz is simply not cut out for it - PiS can and should do better.
More to the point, PiS don't need weak links like him around.
