I like Glenn (with two n's). I haven't listened to him lately because of all the doom and gloom he's been prophesying--not because I don't believe he's right, but just because I can only stand to hear so much doom & gloom. I do believe he's right on the money most of the time.
Glenn, like Mitt Romney (and Harry Reid too, but I'd like to forget Harry exists), is Mormon. Glenn converted to Mormonism some time after hitting bottom in his life due to alcoholism and coming back from the brink of suicide. I believe Glenn offers a unique perspective because of where he's been and what he's experienced in his life. He's seen many issues from both sides and speaks with the voice of wisdom and experience.
