Presidential hopeful Donald Trump's bold and often outrageous comments have bolstered his lead in national polls, but the same can't be said about his business.



The billionaire has his fingers in a number of lucrative pies, from luxury golf courses, hotels, beverages, amusement parks, books and public speaking. His real estate empire, The Trump Organization, brought in $9.5 billion in annual revenue last year, according to media reports.

Despite controversial remarks aimed at Mexicans, Muslims and women, Trump secured him 41 percent backing among Republican voters in the latest Monmouth University survey. While Trump's directness may work in the political process, it doesn't support a business, said Mike Jackson, chief marketing officer at brand image firm Event Solutions International.

"In the past, the Trump name has been aspirational but the field of rhetoric that he's driven though this campaign will do irreparable damage to the brand long term," Jackson told CNBC.

"The Trump brand is primarily a licensing brand. If you're in the business of developing apparel, luxury products, golf courses, are you going to hang that name on your property or product?"
