I wouldn’t read too much into this. Greene’s latest tantrum is just red meat for the populists after they were traumatized by President Trump’s support for the Ukraine bill.
That’s possible, but we could actually be seeing a cooling of affection for Trump by Greene. Trump not only supported the Ukraine funding, but he overall supports Johnson, which is far worse. Greene wanted to keep McCarthy, and wants Johnson gone, and Trump calling her to heel the other day may have set her off.
