Well, the backbone of the Texas GOP is white evangelicals. The only evangelical Protestant-majority town in Poland is Wisła in Cieszyn county in Silesia. I guess we can take it as a rough proxy for the Polish Protestant vote.
In the second round of the 2020 presidential election, which is probably most comparable to an American election, Rafał Trzaskowski received 73.55% of the vote in Wisła. In the first round, Krzysztof Bosak, a candidate literally running as a Confederate
, got 7.5%, which is roughly the same as he got across the region and the whole country.
In other words, the answer is probably 'not very well'. Almost as if these are actually very different countries and this is a silly question.
