But it will take more than the 75-plus remaining days of this campaign to disassemble what it took 70 years of his life to build.

He is who he is.

This fragile narcissist, who is a sort of bottomless pit of emotional need and affirmation, is easily injured by even the slightest confrontation.

He is a man who has said of himself, “I have no friends, as far as I’m concerned,” as he joked that it would be easy to get big money out of politics. But that claim is worrisome, a thing that only a bully would say.

Yes, he can work a crowd, work a screen and work a Twitter account. He can channel anger, hatred and bigotry and give it a voice and face and standing. He can make bombast feel like bravado. He can lower discourse and raise the rabble.

He has the gifts of a grifter.

The problem is that, at the moment, those gifts are proving to be woefully insufficient as he continues to face horrible polling results and other Republican officials begin to reek of fear, panic and impending peril.

Furthermore, his team is being remade in the fourth quarter, as reports of corruption begin to swirl. Last week his campaign chairman, Paul Manafort, resigned after The Associated Press reported:

“A firm run by Donald Trump’s campaign chairman directly orchestrated a covert Washington lobbying operation on behalf of Ukraine’s ruling political party, attempting to sway American public opinion in favor of the country’s pro-Russian government, emails obtained by The Associated Press show. Paul Manafort and his deputy, Rick Gates, never disclosed their work as foreign agents as required under federal law.”

The report continued:

“The lobbying included attempts to gain positive press coverage of Ukrainian officials in The New York Times, The Wall Street Journal and The Associated Press. Another goal: undercutting American public sympathy for the imprisoned rival of Ukraine’s then-president. At the time, European and American leaders were pressuring Ukraine to free her.”

This email controversy, coming from the same campaign trying to make hay of Hillary Clinton’s email controversy. Oh, the irony.
