High-profile defectors such as Tucker Carlson or Marjorie Taylor Greene have accused the president of abandoning his supporters; hawkish Republicans, meanwhile, respond by waving polls that show strong support for the war among those who identify as “MAGA Republicans.”

But the debate about MAGA versus non-MAGA Republicans is obscuring the fact that Trump’s choice........
