Republicans completed a newly introduced two-day midterm convention in Dallas without the disruption party officials had feared, but its electoral impact remained uncertain. President Donald Trump urged voters to act as though he were on the ballot and proposed $5,000 payments to every U.S. adult if Republicans retain both chambers of Congress on Nov. 3, a plan experts estimate would cost about $1.2 trillion and require congressional approval. The proposal energized some activists but was quickly rejected by deficit-conscious Republicans, while lawmakers in competitive districts worried Trump’s message could alienate independents and swing voters. Speakers largely avoided the Iran war and cost-of-living pressures, even as average U.S. diesel prices reached $6.05 a gallon, up 63% from a year earlier, according to AAA. The administration has not specified a funding mechanism, and the dividend’s legal status and congressional prospects remain unresolved. Republicans also face broader economic and political challenges, including a tariff dispute with Canada, weaker approval ratings for Trump, and Democratic efforts to regain Congress.
