> There has been no push or attempted justification for single party politics
He's vocally questioned if the democrats are "traitors" during public speeches[0], a wild accusation even for US political discourse.
> no centralization of power unique to this president
Today, he proclaimed in a speech that Article 2 of the US constitution gives him the right to do whatever he wants[1]. He's spent much of his administration embroiled in scandals involving demanding loyalty from subordinates, and has been repudiated by members of his own party for acting beyond the bounds of his authority.
> no signs of a complete unwillingness to trade
He started a massive trade war to protest the current trade situation with some of the largest players in the global economy. Sure, it's not state capitalism, but his trade strategy directly contradicts both major parties' philosophies regarding trade and is often subject to authoritarian rhetoric.
Sure, this administration doesn't meet all of the classical definitions of what past fascist regimes have looked like.
He may not be making a ton of concrete progress towards consolidating power, but he makes it very clear that he sees himself as having far more power than he actually does, and often gets frustrated when he isn't able to accomplish what he wants. He clearly hates our system of government and isn't afraid to question many of the basic tenets of our democracy.
