A fortnight after Romania, Poland is holding a presidential run-off where the pro-EU candidate faces uncertain odds. On Sunday, Warsaw's liberal mayor Rafał Trzaskowski will need the kind of boost in turnout that propelled his counterpart from Bucharest to victory. Nicoşur Dan came to campaign last weekend for Trzaskowski, the candidate from Polish Prime Minister Donald Tusk's Civic Platform party.

Trzaskowski is not the only one with celebrity endorsements. US President Donald Trump is dispatching his Director of Homeland Security Kristi Noem to stump for nationalist right-wing candidate Karol Nawrocki. The Law and Justice party of Poland's outgoing president Andrzej Duda hopes to rally the 20 percent of voters who veered further to the right in the first round. In a nation where living standards have skyrocketed since joining the EU two decades ago, why are so many citizens eager to elect Eurosceptics?

Would a Nawrocki win call time after just one year on the efforts of Tusk to undo PiS's contentious rule of law reforms? Currently, the former president of the European Council has positioned himself at the heart of Brussels policymaking. Looking ahead, which direction do Poles want?
