Trump has done a makeover of his campaign, to make it…more aggressive. Huh. There was I thinking it was already as aggressive as it was possible to be, short of opening fire on everyone in sight. But apparently I was wrong, apparently it was all bunnies and flowers until now.

He’s hired the top guy at Breitbart to run things. That all by itself tells us all we need to know. Imagine if he’s elected: will Milo Yiannopoulos be Secretary of State?

Donald J. Trump has shaken up his presidential campaign for the second time in two months, hiring a top executive from the conservative website Breitbart News and promoting a senior adviser in an effort to right his faltering campaign.

Stephen Bannon, the executive chairman of Breitbart News LLC, will become the Republican campaign’s chief executive, and Kellyanne Conway, a senior adviser and pollster for Mr. Trump and his running mate, Gov. Mike Pence of Indiana, will become the campaign manager.

Bill O’Reilly for Attorney General! Pat Buchanan for Secretary of Labor!

People briefed on the move said that it reflected Mr. Trump’s realization that his campaign was at a crisis point. But it indicates that the candidate — who has chafed at making the types of changes his current aides have asked for, even though he had acknowledged they would need to occur — has decided to embrace his aggressive style for the duration of the race.

Who knew he’d ever unembraced it? Not I, certainly.

Mr. Bannon has no experience with political campaigns, but he represents the type of bare-knuckled fighter that the candidate had in Corey Lewandowski, his combative former campaign manager, who was fired on June 20.

Mr. Bannon has been a supporter of Mr. Trump’s pugilistic instincts, which the candidate has made clear in interviews he is uncertain about suppressing. He is also deeply mistrustful of the political establishment, and his website has often been critical of Speaker Paul D. Ryan and Senator Mitch McConnell, the majority leader.

Rudolph W. Giuliani, the former mayor of New York City who has become a close Trump adviser, has also urged the candidate to dig in and prepare to fight harder, and in a more focused way, in what has quickly become one of the nastiest presidential campaigns in modern United States history.

Yeah, that’s the ticket! You haven’t been disgusting enough yet, Donnie, be even worse.

The candidate has bucked efforts to rein in his impulsive behavior, committing repeated gaffes after telling his aides he planned to adopt a more presidential tone.

He can only do what he can do. He can’t pretend to be more intelligent or thoughtful or decent than he is, because he doesn’t know how, because he isn’t intelligent or thoughtful or decent enough to know. He’s not equipped to pretend to be “more presidential” because he’s inferior goods.
