https://extranet.sioe.org/uploads/isnie2015/aneja_moszoro_sp... was not the original text I was supposed to translate. The sentence was used in a different text. It's a pity I did not find this link because it would be much clearer then.

rzeczywiście trudno mówić o przetasowaniach jesłi poparcie waha sie pomiedzy dwoma partiami politycznymi, gdzie przymiotnik "swing" oznacza zmiane poparcia albo na przyklad moze być okresleniem stanu ("swing state") ktory nie głosuje tradycyjne zawsze tak samo a na przykład skłania się raz ku jednej raz ku drugiej opcji politycznej.

The US political system is in effect a two-party system: either Democrats or the Republicans are in power on the federal, state, or local level. Therefore, the political deck does not get shuffled in the way it happens in a multi-party parliamentary democracy, where various party alliances are formed or dissolved. Not much shuffling (with two cards in the deck!) going on in here, I am afraid.
