Man, you have to hand it to Dr. Ben Carson.

When politicians switch their allegiance and make surprise endorsements, they usually waffle, wiggle and weasel their way out of answering direction questions as to, “Why?”

Not the doc.

He said he endorsed fellow Republican Donald J. Trump because he couldn’t find another candidate to back, meaning another candidate who (a) could win and (b) fit his own political world view.

There’s another reason: Trump has offered him a spot in a possible (gulp!) Trump administration.

Yep, Carson said so. Out loud. For the record.

Don’t you just love it? I surely do.

Carson’s candor seems to have caught the attention of some legal experts as well. Some have suggested that Trump might have broken federal election law by flat-out “buying” an endorsement by offering a paid position within his administration in the even hell freezes over and Trump is actually elected in November.

New Jersey Gov. Chris Christie is the only other former GOP presidential primary foe to endorse Trump. His own explanation for his switch was so standard. He sought to tap dance all around the fact that he once declared Trump “unfit” to be commander in chief. Now, according to Christie, Trump is, um, “fit.”

Dr. Carson’s candor is refreshing in its way. Politicians are schooled on evasiveness. If you ask a trained pol a direct question about, say, a statement they or someone they support has made, they’re going to revert immediately to a rote response.

It’s as though they’re under some sort of post-hypnotic spell: Ask them a tough question and you trigger a telepathic switch that makes them say what they’re programmed to say.

The good doctor isn’t like that.

I appreciate that he answered so directly: Trump isn’t really my guy. I would have preferred to back someone else. But heck, he made me an offer I couldn’t refuse.

Awesome!
