Dr. Ben Carson, barely two weeks gone from the Republican Party presidential primary trail, has endorsed Donald J. Trump to be his party’s nominee.

The man who Trump called a “pathological liar” now says Trump has another side. The public sees the bombastic Trump, the one who declares Mexican immigrants are rapists, who says John McCain isn’t a “real” war hero, who says Islam “hates America.”

There’s another Trump lurking under the public man’s skin, Dr. Carson said. It’s more nuanced, more thoughtful, that he’s “malleable.”

Can you believe that?

Well, I can’t.

Carson’s endorsement of Trump sounds about as authentic as New Jersey Gov. Chris Christie’s endorsement. Recall that Christie said Trump is “unfit” to be commander in chief; he said Trump is campaigning as “entertainer in chief.”

Now he’s on board. He’s all in.

Christie must be angling for a spot somewhere — I shudder to say this out loud — in a Trump Cabinet.

And Carson? There might be a vice-presidential spot in the good doctor’s immediate political future.

As for his assertion that the “other” Donald Trump is much more likable and implicitly electable, I’ll just add this: If he’s out there, my hunch is that the bombastic and boorish Trump would have given way long ago.
