Nawrocki is anti Putin. The parliament is controlled by liberals, but having a far right president gives the far right veto power. That means the liberals have a hard time passing decent laws. It does not fully block Poland, but it slows everything down and more controversial laws will be vetoed. Controversial laws being everything the far right finds controversial, so a lot of them would be good from a leftist perspective. If PiS wins the next election Poland would move to an Orban style regime again. If the liberals had won, they would have been able to at least slow it down.
