In Dallas, the Republican Party held its first midterm convention, gathering around Donald Trump as their defining force ahead of November's legislative elections. The gathering revealed a party navigating the tension between loyalty to a polarizing leader and the practical anxieties of voters burdened by affordability concerns and the costs of an ongoing war with Iran. From promises of $5,000 dividends to rhetoric about Sharia law, the convention offered a portrait of a movement straining to hold its coalition together while projecting confidence it may not fully feel.
