The same reason Trump does on his website. She is a global Superbrand.
And BTW I wish more people would look at that Trump website, especially his real estate portfolio. This is what he is risking by running for POTUS. If he fails miserably as POTUS that name is going to be worth shiet. There is just no way in hell he is going to allow that to happen. $5 dollar a gallon gas? 10% unemployment? China, Islamos, liberals kicking our ass? No-way-in-hell.
