Missing his own point
Trump seems to be messing up his own brand with this tabloid stuff about Cruz's wife and Cruz's affairs.
THE PROBLEM WITH HEIDI CRUZ IS THAT SHE WORKS FOR GOLDMAN SACHS.
She is deeply involved with Wall Street, therefore Ted also belongs to Wall Street. This doesn't disqualify Ted from running for office. He's already disqualified by being a Canadian, so he shouldn't have been allowed to enter the campaign at all. But the DIRECT Goldman connection should be a constant talking point for an anti-bankster candidate like Trump. Emphasizing the personal stuff distracts and displaces this important brand-identity point.
However .... I shouldn't try to second-guess a master of marketing. Trump is probably confident in his voters by now. He can switch over to
discombobulating his opponent. Seems to be working pretty well.
