Steve Levitsky in The Atlantic:

With the leader of a failed coup back in the White House and pursuing an unprecedented assault on the constitutional order, many Americans are starting to wrap their mind around what authoritarianism could look like in America. If they have a hard time imagining something like the single-party or military regimes of the Soviet Union or Nazi Germany, or more modern regimes like those in China or Russia, that is with good reason. A full-scale dictatorship in which elections are meaningless and regime opponents are locked up, exiled, or killed remains highly unlikely in America.

ut that doesn’t mean the country won’t experience authoritarianism in some form. Rather than fascism or single-party dictatorship, the United States is sliding toward a more 21st-century model of autocracy: competitive authoritarianism—a system in which parties compete in elections but incumbent abuse of power systematically tilts the playing field against the opposition. In his first weeks back in office, Donald Trump has already moved strongly in this direction. He is attempting to purge the civil service and directing politicized investigations against rivals. He has pardoned violent paramilitary supporters and is seeking to unilaterally seize control over spending from Congress. This is a coordinated effort to dig in, cement power, and weaken rivals.

Unlike in a full-scale dictatorship, in competitive-authoritarian regimes, opposition forces are legal and aboveground, and they often seriously vie for power. Elections may be fiercely contested. But incumbents deploy the machinery of government to punish, harass, co-opt, or sideline their opponents—disadvantaging them in every contest, and, in so doing, entrenching themselves in power. This is what happened in Venezuela under Hugo Chávez and in contemporary El Salvador, Hungary, India, Tunisia, and Turkey.

Crucially, this abuse of the state’s power does not require upending the Constitution. Competitive autocracies usually begin by capturing the referees: replacing professional civil servants and policy specialists with loyalists in key public agencies, particularly those that investigate or prosecute wrongdoing, adjudicate disputes, or regulate economic life. Elected autocrats such as Chávez, Vladimir Putin, Recep Tayyip Erdoğan, Viktor Orbán, Narendra Modi, and Nayib Bukele all purged public prosecutors’ offices, intelligence agencies, tax authorities, electoral authorities, media regulatory bodies, courts, and other state institutions and packed them with loyalists. Trump is not hiding his efforts to do the same. He has thus far fired (or declared his intention to fire, leading to their resignation) the FBI director, the IRS commissioner, EEOC commissioners, the National Labor Relations Board chair, and other nominally independent officials; reissued a renamed Schedule F, which strips firing protections from huge swaths of the civil service; expanded hiring authorities that make it easier to fill public positions with allies; purged more than a dozen inspectors general in apparent violation of the law; and even ordered civil servants to inform on one another….
