Various Trump establishments, including his prestigious hotels and golf courses, have decreased in the market share of visits by 14 percent from a year ago, according to industry data.

The main problem facing the Republican nominee, experts told Bloomberg, is the fact that his voter demographic does not match a typical Trump business consumer.

Only 32 percent of families earning over $100,000 a year have a favorable view of the New York mogul.



“The Trump brand used to be one-dimensionally focused on success. It was simple and relevant to a large audience,” said Allen Adamson, the founder of business consulting firm BrandSimple. “Now it’s more complex and polarizing and relevant to a smaller market segment.”



In 2010, only 5 percent of brands were seen as more “glamorous” than Trump's by individuals earning more than $150,000 a year. The same survey last year found that the brand fell about one-third down the rankings list.

The online travel website Hipmunk saw a 58 percent decrease in Trump hotel bookings over the last year alone.



However, despite these numbers, Trump's business executives continue to have high hopes for the brand.



“We continue to outperform our competitors, and we are very enthusiastic about the future and our continued growth,” said chief executive officer of Trump Hotels Eric Danziger.

Trump in the past has been accused of not being able to separate his political and business interests.

His brief announcement that President Obama was born in the U.S., a reversal that was nationally televised from within the newest Trump hotel in Washington, D.C., sparked outrage from some who saw it as mere marketing ploy to draw attention to the new property.
