Dictatorial powers means beyond our legal and constitutional system. That has not occurred. When executive orders or laws went beyond their constitutional authority the courts have blocked those attempts by Trump, Obama, Bush, etc. So, our legal system has prevented any dictatorial powers.
Presidents and politicians have always criticized the press from the nation's beginning (see Adams and Jefferson). None have ever taken over the press.
Elections have often been criticized in our country including huge controversies over the results (1876). These claims of cheating in elections come from the right and left.
So, all those things you claim constitute fascism do not exist in the U. S.
The right uses these same types of claims but uses labels socialism and communism. That makes both sides far from moral and ethical. They uses the same media methods to smear, divert, swivel, and anything else they think will help win support and elections. Increasingly, both sides seem willing to propagate and believe wild conspiracy theories.
