He learned it from Jordan Belfort's Wolf of Wall Street prologue.m, where he says it's a warning...but he clearly isn't contrite nor has made good on his financial penalties. Glenn Beck is just Trainspotting.
Sad though it is to admit, I feel like he's relevant. I just googled him and came back with 74 million hits. Then I tried to come up with a rough equivalent on the left for comparison. Rachel Maddow yielded ~32 million.
Re: the little more together comment. I think he genuinely thought 80% of America agreed with him, and is probably still genuinely confused every time he discovers that isn't the case.
Well said. Like Limbaugh, Beck is an amoral opportunist who doesn't believe a single thing he says. All that matters for Beck is his ability to separate his gullible, frightened fans from their money.
