WASHINGTON (AP) — During his first address to a Republican convention in 2016, Donald Trump had an audacious message to a nation yearning for change: “I alone can fix it.”

A decade later and nearing the midpoint of his final term, Trump is still pitching himself as America’s essential repairman. It’s a strategy that’s helped him overcome daunting odds before but now guarantees this year’s midterms will be a referendum on his unpopular presidency. And it previews how difficult it will be for his party to prepare for a future without him as he shows little interest in ceding the stage.
