You can make that 5 people. Vox is right, he is impossible to embaress which gives him an invincibility almost unseen in nature and completely non-existent in politics.
Edit: the most pertinent exchange of the night:
Q: You've also supported a host of other liberal policies, you've also donated to several Democratic candidates, Hillary Clinton included, Nancy Pelosi. You explained away those donations saying you did that to get business related favors. And you said recently, quote, when you give, they do whatever the hell you want them to do.
TRUMP: You better believe it... I will tell you that our system is broken. I gave to many people. Before this, before two months ago, I was a businessman. I give to everybody. When they call, I give. And you know what? When I need something from them, two years later, three years later, I call them. They are there for me. And that's a broken system.
Q: So what did you get from Hillary Clinton and Nancy Pelosi?
TRUMP: I'll tell you what. With Hillary Clinton, I said, be at my wedding and she came to my wedding. You know why? She had no choice! Because I gave.
