I've never actually watched Glenn Beck on TV, only seen a few YouTubes of him and this is the first book of his I've read. Basically, if you read this Blog frequently, you've seen all this stuff more than once. He has a very odd style of discourse that doesn't appeal to me, but I was actually surprised that the book wasn't nearly has confrontational as both the title and the MSM would lead you to believe.
He defends capitalism, the 2nd amendment, covers education, energy, unions, immigration, the nanny state, home ownership, basic economics, how progressive all our presidents have been since 1900, universal health care, and the constitution. He does generally a good job. He points out what he sees as the most common liberal arguments and then debunks them.
I found his view on home ownership to be interesting. He uses some good statistics to point out that homes are historically not that great an investment. In some places and times -- CA from say the 60's on, etc they have been, but on average, especially without government largess of one sort or another (FHA, mortgage deductions, sub-prime loans, etc).
If you like Glenn and his writing style, there is nothing wrong with the book, read it. If you haven't read a lot of the background books, it may be a good "catch up".
