They already won culturally, as they managed to shift the political culture closer towards theirs. They also managed to set issues that are "theirs". We see the same shit in Europe, were supposedly progressive parties are implementing the wildest dreams of racist anti-immigration, anti-refugee, anti-science and authoritarian surveillance state policies that the fascists dreamed off. All in the name of "stopping" them, while neglecting actually relevant issues like social services and infrastructure investments. Rinse and repeat and by the time the fascists take over all they have to do is remove the remaining formalities of division of power and democracy.
