I doubt Trump will make it to November.

Defending himself against the Kahn family’s charge that, compared to the loss of their soldier son in Iraq, he has never sacrificed anything, Trump asserted that he had sacrificed plenty “building structures” and jobs. He didn’t add that his so-called sacrifices were designed to fatten his wallet.

He sacrificed jobs alright, the jobs of thousands of his employees who were fired following his serial bankruptcies. “I will run the country like I run my companies,” he said. Added former NYC Mayor Michael Bloomberg, “God help us.”

More troubling is that Trump apparently does not even understand what “sacrifice” means.

His failure to understand the term reminds us that one of the duties of a president is to provide comfort to those who stand in grief during periods of loss. Can you imagine Trump providing genuine comfort to the Khan family? To any gold-star family? To the victims of terror attacks in the way that George W. Bush movingly spoke for all of us after 9/11?

Trump cannot provide this comfort because he lacks sympathy for anyone other than Donald Trump. He has been called a narcissist. Definition: a person in love with himself. Narcissists have an exaggerated sense of their own importance. They hate criticism. They demean those who criticize themselves. They have dangerously large and fragile egos. Like children, they act on impulse.

No wonder Trump insults those who disagree with him. “Losers,” he calls them, including American POWs, masking his fear that after Nov. 8 he will be the biggest loser. He can’t accept defeat, which is why he is already talking about a “rigged” election.

And then there is his rank dishonesty. He tells us that he never met Mayor Bloomberg despite photos of him playing golf with Bloomberg. He denied knowing who KKK-leader David Duke is, even though his emails proved he did. Likewise his changing stories about knowing Vladimir Putin. These are not white lies. This is pathological.

He won’t endorse Speaker Paul Ryan for reelection. He has no use for the Republican Party because he isn’t a genuine Republican. He admires Putin and Kim Jong Un and Saddam Hussein.

That’s why Meg Whitman, the former Republican candidate for governor of California, just announced that she will vote for Hillary Clinton.

The most disturbing thing is not that a disturbed man runs for president to satisfy his cravings for attention and power. It is that the party of Abraham Lincoln has nominated him. It’s that most Republican officials will not repudiate him because they put their personal and party political interest above that of their country.

Most but not all.

Senator Lindsay Graham said that he will vote for Clinton because he values the national interest more than his party’s interest. The Bushes and Governor John Kasich and Senator Ben Sasse will not vote for Trump. Likewise about two-dozen other Republicans, including former Treasury Secretary Henry Paulsen, Senator Mark Kirk of Illinois, and Congressman Richard Hanna of Utica.

Some of our best historians, including David McCullough, believe that Trump has already stained a proud political tradition. I join them, confident that the trickle of Republicans who have courageously repudiated Trump will turn into a flood if he lasts until Election Day.
