He always was. He just kept it hid. Trump has caused him and many more secret Clinton and Democrat Party supporters to come unhinged. Consequently, they blew their cover ahead of time.
You just have to ask yourself....everyday that Beck gets up...is he the same guy as he was yesterday, or did some alien UFO hijack Glenn for the 614th time and leave a different Glenn there instead?
Trump keeps ripping the masks and covers off the Clintoon secret agents in DC, Congress, and the so called conservative pundits/mediots like Beck!
