Herman Cain didn't even know what the "right of return" issue is about. He suggested, entirely incorrectly, that Israel would have no problem with the "refugees" returning. I would not use Cain as an example of a person who understands the various issues surrounding Israel - at least until he takes a few refresher courses and gets the basics down.
I didn't hear that being discussed.
I really don't know much about Cain. Maybe he doesn't know much about the "right of return." My impression from what I did hear today is that when he does know about it, his judgment about it will be correct.
