What does it mean in other words?
but he makes sure there’s something about him that different people can relate to, personally.

THE CONTEXT:

First, for the skeptical, don’t underestimate the man. Why is a regular guy attracted to a billionaire candidate? It’s simple. Because he can “play to people’s fantasies,” as Mr. Trump puts it. The man knows his television, loves money, hates rules, tells jokes, uses bad language and is convivial to a fault. He may not be like us, but he makes sure there’s something about him that different people can relate to, personally.

Answer

I would interpret it that because the man's a billionaire candidate, he's not like most normal people, so he can't relate to people in that regard. However, despite this difference in money and lifestyle with other people, he purposely acts in such a way that lots of different types of people can still relate to him on a personal level and have similarities with him.
