To use pro-wrestling terminology, this is an obvious “work.”
The goal of this setup is to continue to shore Ramaswamy up as one of the “good Republicans” so that those people who still identify as Republicans but who also consider themselves “one of the good Republicans, small government yadda yadda, not one of those bigoted ones!” and are at risk of leaving the party over its overarching fascism can latch onto him in this interview and still keep that R after their names. Meanwhile, the Republicans who agree with Coulter can cheer for her side of this.
The Republican party is more and more openly nazi every day. Stunts like this - including the whole phenomenon of Ramaswamy as their “look we’re not racist, we have an Indian friend!” token - are to keep the party’s numbers bulked up with enough unsuspecting “decent” people to empower the nazis at the top continue to nazi in all their names.
