In a post on X, the head of the President's International Policy Bureau said the election results had brought a change, with Democrats winning after previous Republican victories.
Przydacz also described the result as a reminder to Prime Minister Donald Tusk and his team that no government lasts forever and that Polish voters would eventually decide on a change.
Presidential Chief of Staff Zbigniew Bogucki told Telewizja Republika that Republicans had not won the midterms but had not suffered a crushing defeat either.
Asked whether the change in the US balance of power could reduce the chances of a permanent American base in Poland, Bogucki said history shows that changes in Washington can bring changes in policy.
He said there was currently a green light for a permanent base or a permanent US troop presence, but no legislation had yet been introduced to implement the political decisions.
He added that the government supported the idea in principle but had not presented details.
The issue of a permanent US base was discussed at Tuesday's National Security Council meeting. After the meeting, Przydacz expressed hope that the government would speed up work on the US military presence, saying 15 months had passed since the first talks while the government was still discussing whether there should be one, two, five or ten bases.
Defence Minister Władysław Kosiniak-Kamysz said the permanent US base was a goal the government had been working towards for months and that the council had confirmed it as a shared priority.
