From the March 16 edition of Fox News' The Five:
GREG GUTFELD (CO-HOST): The most sensible assessment of Rubio's downfall probably comes from Mickey Kaus, who said that you look at someone like Rubio who has all these positives, you know, and he seemed to be performing best against Hillary. However there was one thing that brought him down, and it was immigration. And when Trump made it that issue, there was no way that Rubio could ever get back up, you know, and reach a stature on that level because that was the thing that would bring him down. Trump, I think, you know, people talked about the insider versus outsider. I don't think it's about that. I think it's about immunity. Where Obama, and I've said this before, had the historical first immunity. The first black candidate. That allowed him a measure of immunity about his history, a lot of people, you know, he didn't have a long, you know, resume of achievement, it didn't matter. Trump had an immunity bubble, and has it today, as being an entertainer.
