What happens after the Polish Elections?

Professor Sadurski, in your recently appeared book “Poland’s Constitutional Breakdown”, you show what tremendous damage the PiS government has wrought on Polish constitutional democracy during its first term of office. In a few weeks, there will be Parliamentary elections in Poland, and Presidential elections will follow next year. The polls are not exactly promising regarding a change of government and it might very well be the case that the Law and Justice party (PiS) might tighten its grip on power. What would that mean for Poland?
