Trump’s own diagnosis of his campaign’s shortcomings led to this unusual prescription—which is the diametric opposite of what most Republicans have been counseling for their embattled nominee. “The campaign has been too lethargic, too reactive,” says a senior Trump official. “They wanted to bring in someone who understood new media, understood digital. It’s not going to be a traditional campaign.” Trump was frustrated by Manafort’s efforts to contain him and angry about his plummeting poll numbers. With Bannon in the fold, the source adds, Trump will feel free to unleash his inner Trump: “It’s very simple. This is a change election. He needs to position himself as anti-establishment, the candidate of change, and the candidate who’s anti-Washington.”

The shake-up is an ominous development for Republican elected officials alarmed at Trump’s collapse and the effect he could have on down-ballot races across the country. In recent years, Breitbart News has bedeviled Republican leaders, helping to drive out former House Speaker John Boehner and, more recently, making life difficult for his successor, Paul Ryan. Last fall, at Bannon’s insistence, Breitbart reporters visited Ryan’s Wisconsin home (which is surrounded by a wall) and published a story shaming him for not endorsing Trump’s proposal to erect a wall along the Mexico border.

Bannon, who’s as eager to attack Republicans as Democrats, is unlikely to worry much about the plight of mainstream GOP incumbents. At a New Year’s party at his Capitol Hill home last year, Bannon gave guests silver flasks stamped with his personal motto: “Honey badger don’t give a shit.”
