This link to the 6 minute interview does not fit the Headline. Glenn in NO WAY admits he’s been wrong about Trump and continues to bash and mock him for six minutes. I wish we would have headlines that match the content, but I guess there would be no way to get folks to check out the articles (if even they do). It’s rather deceptive, really.
I got the impression that Beck was merely admitting that he did not think Trump would get this far, not that he was coming round to Trump's way of thinking. Beck is a whack job.
It’s a direct quote from Beck, at 4:05 in the linked interview. Play it. The headline does match the content. The content qualifies the headline quote, and quotes Beck further to clarify.
