As American midterm elections approach, the Republican Party finds itself navigating a familiar but deepening tension: its most powerful figure is charting a course that diverges from the party's collective strategy on Iran, the economy, and beyond. This is not merely a dispute over policy — it is a test of whether a political movement built around one man's appeal can hold together when that man refuses to be bound by it. The gathering in Dallas becomes less a strategy session than a reckoning with what the party actually is, and what it can credibly offer voters who are watching closely.
