The way Donald Trump keeps going on about Khizr Khan, the father of a fallen soldier who denounced him from the podium at the Democratic National Convention, you would think that he was confusing the old gentleman with Khan Noonien Singh, the supervillain from “Star Trek.” That the matter has persisted for almost a week tells us one thing (and one hates to say it.) #Donald Trump lacks the temperament to be president of the United States. He is not likely to acquire that temperament, barring divine intervention.

Trump can certainly still win against Hillary Clinton. She is that evil and corrupt and would likely be an even worse president than Trump ever could be. But surely the country deserves more of a choice between, as the late Molly Ivins said, the evil of two lessers.

Trump claims to be running for president out of regard for his country, leaving a life of wealth and power to offer solutions that he feels would best address the problems that the United States is afflicted with. He is surely not on some ego trip for the purpose of feeding his need for self-aggrandizement.

Trump should, therefore, prove it. He should withdraw from the presidential race.

The move would be unexpected and would be a game changer in the election. Trump could call a press conference or appear on a national cable news show like Hannity or O’Reilly to make the announcement.

He should state that it has occurred to him that he has become the issue in the race and not the problems that need to be addressed. He should, if he can bring himself to it, apologize for letting his supporters down. Then he should retire into the bowels of the Trump Tower and not come out until after the election.

With Trump out of the race, the Republican National Committee would have to meet quickly to choose a new candidate. That man will likely be Mike Pence, the current vice presidential candidate. The new vice presidential candidate should be someone that Gov. Pence wants. The Republican Party is replete with talent in this regard, with the top favorites being Newt Gingrich and Sen. Ted Cruz.

Of course, when they get over their shock, Team Hillary will go after Pence with as much fury as they have against Trump. But the attacks will be with far less credibility. Pence will have two qualities that Trump and Hillary Clinton lack, sanity and propriety. He will have more than an excellent chance of winning and then give honor to the office of the presidency.   #Election 2016 #MikePence
