When putative Republicans such as Sen. Mitt Romney (R-Utah) are criticizing the president — and others like John Bolton, former national security adviser, are signing deals for books that are rumored not to be friendly to their former boss — one alum of the Trump administration has no patience for disloyalty.

And she had no patience for it, either, during her time as the U.S. ambassador to the U.N.

That would be former GOP South Carolina Gov. Nikki Haley.

If, as is thought by many, she is considering a 2024 run, this is a very smart tack to take.

It’s a policy she makes crystal clear in her new book, “With All Due Respect.”

The administration has taken note.

See this tweet.

As she related to CBS News on Sunday, Haley took great umbrage when former Secretary of State Rex Tillerson and former Chief of Staff John Kelly tried to involve her in subterfuge against the president by going to her, instead of to President Donald Trump, with their problems with the chief executive.

“Instead of saying that to me, they should’ve been saying that to the president, not asking me to join them on their sidebar plan,” Haley said to “CBS Sunday Morning.”

Trump fired Tillerson in 2018 and Bolton left the administration — there are conflicting accounts as whether he resigned or was fired — in September of this year.

“It should’ve been, ‘Go tell the president what your differences are, and quit if you don’t like what he’s doing.’ But to undermine a president is really a very dangerous thing.” Haley said.

“And it goes against the Constitution, and it goes against what the American people want.”

“And it was offensive.”

John Kelly wasted little time in responding to her comments.

His spin notwithstanding, Kelly does not deny what Haley charges.

He merely attempts to rationalize it as an actual service to the president.

Haley also supports the president on impeachment: “The Ukrainians never did the investigation. And the president released the funds. I mean, when you look at those, there’s just nothing impeachable there.”

As the GOP begins to look at the outline, one way or another, of a post-Trump world, Haley has been on the short list of presidential material.

She’s from an immigrant family; she’s smart, telegenic, and sports a successful record as the governor of South Carolina. Her image is of a tough conservative leader who could handle herself and then some in the piranha-infested waters of national politics.

Yet, because of her gender and her moderate manner, to some she would be a welcome rhetorical respite from the combative Trump years.

She may even be able to being the 5 percent to 10 percent of GOP Never-Trumpers back into play in a presidential race.

It would also greatly amuse Republicans — and anger beyond sanity the Democrats — if the first woman to become president of the United States was a conservative Republican.

For that reason and more, she is a person worth watching now and in 2024.
