But the presidency is different. It can give him a legitimacy that has long eluded him and expose the Trump brand to a wider audience -- including a worldwide one from which he can continue to expand his entertainment properties and increase his net worth.
Given the opportunity to be remembered as FDR, who helped America recover from the Great Depression, or Merv Griffin, creator of "Jeopardy!" and "Wheel of Fortune," two of the most lucrative and longest-running game shows, I suspect I know which one Donald Trump would choose.
Reality TV and social media have helped blur the lines between entertainment and reality. Trump is hoping they stay blurred long enough for him to pocket some serious Benjamins.
