The ‘we-know-better’ conventional wisdom of pundits is that she’s actually running for the Vice Presidential nomination. I’m not certain the pundits are correct, or that she’d even accept that semi-vestigial role if offered.
My general impression is that Haley is an impressive person with a good resume who might well be a good president if she could get elected. Of course I’d say those exact words for Mike Pompeo, if he runs, and mean them just as strongly. And it would be nearly as true of Mike Pence.
The GOP has a strong bench, maybe too strong. If all of these people plus DeSantis run in ‘24 Trump probably gets the nomination as he has a substantial reservoir of good will among GOP stalwarts - enough to make him first-among-equals in a scatter-shot race with many good candidates splitting the not-Trump vote.
Later … A knock on Haley that I believe has merit - she has not been a reliably fierce culture warrior in the way Trump, Youngkin, and DeSantis have been. Likewise, Pompeo has no demonstrated chops in the culture war arena, it’s an area in which Kristi Noem has also come up short.
