Trump is many things, and charismatic may be one of them, although personally I don't see it, but "a powerful builder" is not one of them.
Trump doesn't build buildings - he licenses his name to buildings other people build. He doesn't even own most of the properties that bear his name. The only thing he can feasibly claim to have built is his own celebrity, and prior to his recent status, his celebrity might generously be described as b-list - he was a reality show star who was once a professional wrestling celebrity heel and sometimes guest starred as himself on various tv shows.
The distinction is important, I believe, because to me, "builder" implies someone with a passion and a deep understanding of the art of whatever they make their living at. I don't see a passion about architecture or design from Trump, nor do I get a sense that he understands how they work, or that he cares.
