Trump promises ‘no new deals’ while president, Ivanka won’t manage company

I predict Trump will 'dither' on his business strategy while in office ( assuming he gets that far) so as to force the Party's hand in removing him from his business affiliation to his ongoing management involvement. There are several other excellent potential replacements for a Trump president so why are we taking a chance on a very disliked President elect, a ensuring a potentially malfunctioning Trump Presidency?
