Donald Trump has shifted his tone on former President Jimmy Carter, whom he once sharply criticized. Trump now faces similar challenges, like inflation and the war in Iran, which has led to comparisons between their presidencies. Last month, Trump mentioned Carter while discussing Iran, reflecting on Carter's failed 1980 hostage rescue mission. Although Trump still criticizes Carter, he has expanded his comments on past presidents, including Democrats, as he mulls his own historical legacy. While Trump has somewhat softened his rhetoric, major differences remain between the two leaders, especially in their personal lives and their approach to most major policy issues.
