Michelle Obama’s nationwide tour for her new book “Becoming” has already helped the book achieve a publishing milestone.

Barnes & Noble said Monday that Obama had “the biggest first-week sales of any book this year.”

Until November, that title belonged to Bob Woodward’s Trump administration dissection, “Fear,” which came out in September. But “Becoming” had even stronger sales in its first week, the bookseller said.

Beyond just this year, B&N said “Becoming” had “the best first-week sales of an adult book since ‘Go Set a Watchman’ published in July, 2015.”

It has been nearly two years since the Obamas left the White House, but there is still intense interest in the former president and first lady.

“Becoming” remains No. 1 on the online lists kept by both the Amazon and Barnes & Noble websites.

Her book landed in Amazon’s No. 1 spot on Friday, November 9, and has not budged since.

A gauntlet of TV interviews, including all three network morning shows, surely helped sales.

The interviews will continue later this month. On Friday, November 30, she will be on “The Late Show with Stephen Colbert.”

“Becoming” came out on November 13. It is almost certain to rank No. 1 on the New York Times best selling books list, but that list won’t officially come out until Wednesday.

All the interest in the title — plus her nationwide arena tour — has stoked new speculation about her political prospects. Is there any chance she’d run for political office?

“Let me be very clear, it will never happen,” Obama adviser Valerie Jarrett told Alisyn Camerota on “New Day” Monday morning.

As for Obama’s husband, he is working on finishing his own memoir. Both books were acquired by Penguin Random House in a bidding war back in early 2017.

“Writing’s hard,” Barack Obama said at his foundation’s annual summit on Monday. “I’m just sitting there, I type two words… delete.”

His remarks about the difficulties of writing were reported by The Atlantic. He reportedly told people to go buy his wife’s book.
