I had seen where that group wasn’t going to vote for Trump even after Haley endorsed him, and that they said if Biden did step aside they would still never vote for Trump, but might be open to President Biden’s replacement - depending on who it was: I guess Harris is acceptable to them. Not surprising, really, as that group supported President Biden before he stepped aside, and Vice President Harris is equally as good and decent of a person as President Biden is.
Vice President Harris is also the ACTUAL law and order candidate of the two remaining, (like President Biden was before her) so that definitely would appeal to former Nikki Haley voters.
