Well, Glenn has certainly caught a lot of flack on excerpts I see in the news;
But listening this morning and the whole theme of the show seemed to be that Kasich made a deal with Trump and that Kasich was siphoning votes off of Cruz. Beck's reasoning was because Kasich withdrew just hours after Cruz.
And some Beck listener from Ohio towards the end of the 2nd hour went along with this.
This theory is totally wild speculation on Beck's part as far as I can see, maybe the Blaze has something.
