The Washington Post Opinion: Only one 2020 Democrat fully grasps the threat Trump poses. By Greg Sargent.

“Thus, Warren’s call for an impeachment inquiry is linked to a big argument — one broader than that of any other candidate — about how the GOP has actively enabled Trump’s authoritarianism, lawlessness, shredding of governing norms and embrace of the corruption of our political system on his behalf.

Warren is comprehensively treating Trump both as a severe threat to the rule of law in his own right, and as inextricably linked to a deeper pathology — the GOP’s drift into comfort with authoritarianism.

Trump’s authoritarianism and his corruption are two sides of the same coin. Trump’s tax returns, which he rebuffed a House request for — something his government participated in, with dubious legality — may conceal untold levels of corruption, from possible emoluments-clause violations to financial conflicts to compromising foreign financial entanglements.

Warren has responded to all this — and the GOP’s near-total comfort with it — by rolling out a sweeping anti-corruption measure that requires presidential candidates to release tax returns and requires divestment to avoid such corrupting situations in the future.

Thus, Warren is treating this two-sided coin of authoritarianism and corruption as a systemic problem in need of reform, one linked to the broader imperative of actually “draining the swamp,“ as Trump vowed, only to plunge into full-scale corruption himself.”
