In a speech to about 550 people in Tucson, Arizona, Trump insisted he had scored a “monumental victory” in the debate, referred to Minnesota governor Tim Walz as the vice president, slurred his words, and appeared to be having trouble reading off the teleprompters. CNN tonight compared one of Trump’s 2016 debates with Hillary Clinton to his performance on Tuesday, and the difference was stark.

Psychiatrist Richard A. Friedman wrote in The Atlantic today that Trump is showing signs of cognitive decline. His tangents and inability to get to a point suggest “a fundamental problem with an underlying cognitive process.” “If a patient presented to me with the verbal incoherence, tangential thinking, and repetitive speech that Trump now regularly demonstrates, I would almost certainly refer them for a rigorous neuropsychiatric evaluation to rule out a cognitive illness,” he wrote.

Trump continues to try to dominate the political debate by refusing to back off any of his assertions, doubling down on the lies about immigrants eating pets and teachers giving students sex change operations. He called Harris a “Marxist communist fascist socialist,” clearly just stringing words together.

Meanwhile, he is giving off vibes of desperation. This afternoon he announced he would launch his crypto platform “World Liberty Financial” on X Spaces on September 16, hardly the sign of a presidential candidate convinced he’s about to regain his position as the leader of the free world.

It has been notable for a while that Trump’s wife, Melania, is nowhere to be seen, and Trump has begun to cling to provocateur Laura Loomer, who has vowed utter loyalty to Trump and is evidently quite happy to be seen with him. This is a problem for the Republican Party because of her history of conspiracy theories and open racism. As Joe Perticone and Marc Caputo of The Bulwark note, Loomer has referred to Vice President Harris as a “drug using prostitute,” for example, and suggested she has not given birth to children because “she’s had so many abortions that she damaged her uterus.”

Loomer’s extremism has made other Trump supporters urge him to keep her at a distance, sparking an embarrassing public fight. Two of those trying to get Trump to isolate Loomer are Senator Lindsey Graham (R-SC) and Representative Marjorie Taylor Greene (R-GA). Their chilliness prompted Loomer to fight back on social media, questioning Graham’s sexual identity and calling attention to Greene’s extramarital affair and comparing her to a “hooker.”
