Donald Suffers First Golf Business Hit In Celebrity Apprentice Finale Publicity Tour

I mean, his possible presidential run. From Abe Sauer at Brand Channel:

Given that Trump's courses are almost all private, it might seem unlikely that a politicization of his name would have much of a positive impact on his business. But it's already happened. 

In April, the African American Chamber of Commerce of New Jersey canceled its golf classic event at the Trump National Golf Club Philadelphia to protest Donald Trump's hissy fit over President Obama’s birth certificate. That's lost business. (Though some have suggested Trump might be okay with this particular loss.)

Even better was this link to a documentary trailer on Trump's battle to get his Scotland course built.
