source close to Trump tells @KatyTurNBC candidate's children unhappy w/Bannon/Conway/Bossie leadership, think campaign is hurting business— John Harwood (@JohnJHarwood) September 28, 2016
Sure. It's the people who have been running the campaign for two minutes or whatever. Nothing to do with the candidate.
Don't get me wrong: Steve Bannon and Kellyanne Conway and David Bossie are terrible. But it's hardly their fault, exclusively or even primarily, that Trump's business is suffering.
His business is suffering because he has revealed himself to be a nightmare bigot to whom lots and lots of people never want to give another dime of their money.
I'm guessing the fact that this campaign has also exposed the fact that Trump has a habit of refusing to pay people for the work they did for him, running scams and frauds, and generally being not a great guy to do business with has had an impact, too. Just a thought!
