Is that true in all of Poland though? Many people find Trump repulsive, and they will agree with most of their peers if they move to a big city in a blue state.
Big cities (capitals of subregions and anything over ~150 000 people) are liberal, small cities and countryside is conservative. Western and northern Poland has more people in big cities so it's liberal, Eastern and southern Poland has more people in countryside so it's conservative. Overall more people live in the conservative parts, so Poland is conservative, but the exact division changes with each elections, previously we had 2 terms of "liberals".
