Executive summary: Donald Trump’s predominant personality patterns are Ambitious/exploitative (a measure of narcissism) and Outgoing/impulsive, infused with secondary features of the Dominant/controlling pattern and supplemented by a Dauntless/adventurous tendency. This particular personality composite can be labeled amorous narcissism or, in political terms, high-dominance charismatic — charismatic by virtue of the highly elevated primary Ambitious–Outgoing amalgam.

Executive summary: Donald Trump’s core personality-based leadership traits may be summarized as follows: an active-positive presidential character with mobilization — the ability to arouse, engage, and direct the public — as his key leadership asset; an overall leadership style that is distinctively charismatic and nondeliberative; and a high-dominance, extraverted, influential foreign policy orientation.

The Personality Profile and Leadership Style of U.S. President Donald J. Trump in Office
By Aubrey Immelman and Anne Marie Griebie
July 2020
Summary and Formulation
This paper presents the results of an indirect assessment, from the conceptual perspective of personologist Theodore Millon, of the personality of Donald J. Trump, 45th president of the United States, based solely on personality dynamics revealed by his political behavior in office.
Psychodiagnostically relevant data were collected from biographical sources and media reports of Trump’s postinaugural political behavior from January 20, 2017 until July 2020 and synthesized into a personality profile using the Millon Inventory of Diagnostic Criteria (MIDC), which yields 34 normal and maladaptive personality classifications congruent with DSM-III-R, DSM-IV, and DSM-5.
The personality profile yielded by the MIDC was analyzed in accordance with interpretive guidelines provided in the MIDC and Millon Index of Personality Styles manuals. Trump’s primary personality patterns were found to be Ambitious/self-serving (bordering on exploitative), Dominant/controlling (bordering on aggressive), and Outgoing/gregarious (bordering on impulsive), infused with secondary features of the Dauntless/dissenting pattern. There is suggestive, equivocal evidence of incipient Distrusting/suspicious and Erratic/unstable tendencies emerging during Trump’s time in office.
Ambitious individuals are bold, competitive, and self-assured; they easily assume leadership roles, expect others to recognize their special qualities, and often act as though entitled. Dominant individuals enjoy the power to direct others and to evoke obedience and respect; they are tough and unsentimental and often make effective leaders. Outgoing individuals are dramatic attention‑getters who thrive on being the center of social events, go out of their way to be popular with others, have confidence in their social abilities, tend to be impulsive and undisciplined, and become easily bored — especially when faced with repetitive or mundane tasks. Dauntless individuals tend to flout tradition, dislike following routine, sometimes act impulsively and irresponsibly, and are inclined to elaborate on or shade the truth and skirt the law.
As predicted on the basis of his pre-inaugural personality profile, Trump’s executive leadership style in office was bold, competitive, and self-assured (i.e., ambitious); tough and directive (i.e., dominant); impulsive and undisciplined (i.e., outgoing); and disruptively tradition-defying, with an inclination to shade the truth and skirt the law (i.e., dauntless).

Presidential Electability Index (political impact) score

Who will win the 2024 Republican presidential nomination?
January 14, 2021
Trump drops 12 points: According to a POLITICO/Morning Consult poll released on Wednesday [Jan. 13, 2021], 42 percent of Republicans said they would vote for Trump in the 2024 presidential primaries in a poll conducted Jan. 8-11, after the attack on the Capitol. That percentage is down from 54 percent of Republicans who said they would vote for Trump when the question was asked Nov. 21-23. …
Despite the drop in numbers, Trump is still ahead of other potential challengers. The poll found 16 percent of Republicans said they would vote for Vice President Mike Pence; 6 percent for Donald Trump, Jr.; 6 percent for Sen. Ted Cruz (R-TX); 5 percent for Nikki Haley, the former South Carolina governor and American ambassador to the U.N.; and 6 percent said they would vote for Sen. Mitt Romney (R-UT). …
Opening yesterday, the [PredictIt] market tracking who will lead the Grand Old Party into the next presidential election showed Trump as the top contract at 19¢. He was followed by Haley at 16¢, Pence at 13¢ and then two senators at 8¢.

Excerpts
The eight Republican presidential candidates who took the stage last night had a lot going for them. … In a different year, the race among them might be a fascinating one.
But the 2024 Republican campaign is shaping up to be unlike any in memory.
Donald Trump remains so popular among Republican primary voters that there is no obvious path for any of the other candidates to displace him. He leads among virtually every Republican subgroup: both men and women; those with household incomes above and below $100,000; evangelicals and non-evangelicals; moderate and conservative Republicans; Fox News devotees and people who get their news elsewhere; and in each region of the country, as well as in rural areas, suburbs and cities. …

New York Times/Siena Poll, July 23-27, 2023
For more than eight years now, since he declared his 2016 candidacy in New York, Trump has dominated the Republican Party, notes our colleague Shane Goldmacher, who covers politics. Many Republicans — a long and varied list starting with Jeb Bush, Marco Rubio and Ted Cruz in 2016 — have tried to displace Trump, without success. Neither Trump’s loss to Joe Biden in 2020 nor the poor performance of his preferred candidates in the 2022 midterms nor the four recent indictments have altered the situation. …
