Other signs point to the gradual erosion of Trump’s influence. Candidates may seek his support, but those who fail to get it don’t drop out of the race. Trump’s endorsement of Alabama Rep. Mo Brooks for his state’s open Senate seat did not dissuade Katie Britt, a former chief of staff to retiring Sen. Richard C. Shelby, from entering the race on Tuesday. Her three-minute announcement video barely mentions Trump and strikes traditional conservative themes of faith, family and hard work... Trump’s own behavior supports the idea of waning power. He is not trying to influence congressional deliberations at all, leaving legislative strategy to party leaders such as Senate Minority Leader Mitch McConnell (Ky.). The more lawmakers act without Trump’s guidance, the harder it will be for Trump to reestablish his dominance later. Trump also canceled his online blog after less than a month because so few people were reading it. The demand for Trump may be a mile wide, but it seems only a few inches deep among a majority of Republican voters. It’s hard to see what Trump can do over the next year to strengthen his standing. His decision not to engage in any serious legislative fight will keep him out of the news while potential rivals such as Florida Gov. Ron DeSantis use their positions to curry favor with Republicans. DeSantis is aiming for the party’s sweet spot — Republicans who like Trump’s agenda but are ready to move on from him. An April Echelon Insights poll found that only 41 percent of GOP voters want a party that is led by Trump. Thirty-eight percent take less positive views toward Trump’s future role, with the party’s center being the 21 percent who want a party that supports Trump’s “America First” agenda but is not led by him. As more potential candidates such as DeSantis show that a Trump-like party shorn of his toxic elements is possible, the more Republicans will leave Trump behind.
