Trump publicly tore into a group of former allies, a sign of a widening split on the right that could matter for the next election.

• Trump called Tucker Carlson, Marjorie Taylor Greene, Thomas Massie and Joe Kent "losers" and mocked the idea of Carlson running for office.
• The worry inside the party: a Carlson-led third-party or spoiler run would pull votes from Republicans, not Democrats.
• Trump still holds the base — his primary endorsements this year have won almost every race.
• JD Vance is the quiet target here, since he is close to Carlson and would inherit the fallout.
• The split is likely smaller than it looks, with only a sliver of Republican voters siding with the breakaway group.

Outlook: Expect more public sniping as 2028 positioning starts early, but a serious Carlson run still looks unlikely.
