When someone tells you who they are, over and over, in words and actions, BELIEVE THEM! DJT is an abomination who openly talks about how he will dismantle our democracy, violate the Constitution, and take vengeance on his perceived enemies using the apparatus of a government filled with cronies he installs.  See:

Jamelle Bouie in the NYT : “And Donald Trump is telling us, loud and clear, that he wants to end American democracy as we know it.”

Eric Foner in the NYT: “President Trump announced that he plans to issue an executive order ending birthright citizenship, the principle that everyone born in the United States, with a handful of exceptions, is automatically a citizen of the United States.“It was always told to me,” the president declared, “that you needed a constitutional amendment. Guess what? You don’t.””

Catherine Rampell, WashPo, quoting DJT: “If I happen to be president, and I see somebody who’s doing well and beating me very badly, I say, ‘Go down and indict them,’” he said. “They’d be out of business. They’d be out of the election.”

Heather Cox Richardson in her Letters From an American, also quoting the weirdly bronzed one: “In honor of our great Veterans on Veteran’s Day [sic] we pledge to you that we will root out the Communists, Marxists, Racists, and Radical Left Thugs that live like vermin within the confines of our Country, lie, steal, and cheat on Elections, and will do anything possible, whether legally or illegally, to destroy America, and the American Dream”

David Graham, writing in the Atlantic: “In fact, much of what Trump is discussing is un-American, not merely in the sense of being antithetical to some imagined national set of mores, but in that his ideas contravene basic principles of the Constitution or other bedrock bases of American government. They are the sorts of ideas that would have been shocking to hear from any mainstream politician just a decade ago.”
