Donald Trump’s self-obsession, his uncontrollable urge to take credit for everything and to toss aside blame for anything, simply affirms what some of us have said since the moment this guy declared his candidacy for president of the United States.

His entire adult life has been calibrated for self-enrichment, self-aggrandizement, self-promotion.

The president issued some kind of statement over the weekend about the things for which he is grateful. Did he mention the blessing that have come his way? Did he talk about his family? Did he speak to the liberties we enjoy as Americans? No. He spoke to the “tremendous difference” he has made on the nation.

He was delivering remarks at a recent White House ceremony in which he honored several Americans with the Presidential Medal of Freedom. The president just couldn’t resist taking personal credit for the nation’s stellar economic performance.

He gives himself an A+ grade as the first half of his term approaches.

Time and time again — and I cannot even think of all the instances he’s done this — Donald Trump turns everything inward. He internalizes every single thing he deems to be a positive development.

I have been saying since the moment he began his political career — which commenced on that escalator ride in Trump Tower when he announced his candidacy — that Donald Trump’s entire life has been geared toward his own enrichment. Public service is a totally foreign concept to this man. He’s been president for nearly two years and it’s still a foreign concept.

He cannot empathize with those who face nature’s wrath. He doesn’t appreciate the service others give to the nation. Trump doesn’t grasp the need for him to step forward as the nation’s consoler, a sort of lay pastor, someone who ministers to a nation in mourning.

Fires exploded in California and he blamed the state’s forest management policy. When a hurricane savaged Puerto Rico, the president said it wasn’t a “real tragedy” such as what happened in 2005 when Hurricane Katrina stormed ashore; then he got into a terrible feud with the mayor of San Juan.

It’s all about Trump. All the time.

Moreover, it is totally consistent with this individual’s life before he became a politician. Many of us saw it from the beginning of his campaign for the presidency and rejected it; others embraced this man and his self-aggrandizing nature.

What I cannot fathom is how those who embraced it then continue to do so now.
