Marjorie Taylor Greene this week escalated her break from Donald Trump into something broader and more structural than a personal political dispute, publicly framing the MAGA movement as having split into two distinct and incompatible factions.

In a post on X accompanied by an image of two columns, she placed herself alongside Tucker Carlson, Megyn Kelly, Candace Owens and Alex Jones as representatives of what she labelled “Old MAGA,” characterised by America First domestic priorities and opposition to foreign wars. In the opposite column under the heading “New MAGA” she placed Ben Shapiro, Laura Loomer, Fox News host Mark Levin and Florida Representative Randy Fine, figures she associates with hawkish Iran war support.

“We need Alex Jones added to Old MAGA, which is America First, and New MAGA, which is really MIGA, needs Lindsey Graham,” she wrote, using an acronym suggesting the movement had become “Make Israel Great Again” rather than America First. The taxonomy was Greene’s most direct attempt yet to organise the anti-war MAGA constituency into a coherent alternative bloc rather than simply a collection of individual dissenters.

Trump responded on Truth Social the same day by calling Carlson, Kelly, Owens and Jones “LOSERS” and “NUT JOBS,” accusing them of fighting him over Iran policy to grab media attention on podcasts. “They oppose me because they want Iran to have nuclear weapons,” the president wrote. The response simultaneously validated Greene’s framing by confirming the split was real, and illustrated the difficulty of maintaining a unified conservative coalition while pursuing a war that a meaningful segment of its base believes was never part of what they voted for.

Greene’s own X post directly addressed the moment: “President Trump has gone mad as he wages war against Iran, a broken campaign promise. I fought alongside Tucker Carlson, Megyn Kelly, Candace Owens, and Alex Jones to help get Trump elected. And now he goes off on a rambling rant attacking all of us in one post. We NEVER changed, Trump did. AMERICA FIRST!!!”

Candace Owens responded to Trump’s attack by posting “It may be time to put Grandpa up in a home,” a remark that circulated widely and added personal dimension to what had been a policy dispute. Laura Loomer, whose loyalty to Trump has remained intact, fired back at Greene directly: “I’ve been MAGA long before you. You’re such a joke.” Loomer has been a consistent antagonist toward Greene since the resignation, accusing her of bullying Trump and deliberately creating conditions for Republican losses.

The midterm subtext running through all of it is the one Greene has been most explicit about raising. At least 36 House Republicans have already announced they will not seek re-election in November, leaving the party’s 216-213 majority in what most observers consider irreversible jeopardy. Greene has pointed specifically to a Texas primary in which Democratic turnout exceeded Republican turnout as an early warning signal that the Iran war is energising the opposition in ways that the party’s current leadership structure is not equipped to counter. She has publicly predicted Republicans will lose the House, framing the outcome as a direct consequence of Trump’s break from his 2024 campaign promise of no more foreign wars.

Trump has not acknowledged any electoral vulnerability in his own choices, and his approval ratings, running in the 35 to 39 percent range overall and 22 percent among independents according to multiple methodologies, reflect a second-term political environment considerably more exposed than the first.
