I've read this book with much expectation, it was very boring all through out the book
Solution: Negative
Why? Review writer does not like the book because it was boring, therefore it is a negative review.

New input: There is no room for RINOs (Republicans in Name Only) in our fight to win over the general population concerning the merits of conservative principles. Horowitz's book documents the fact that rightward ideas are winning ideas and will resonate with voters across the nation. This is a collection of essays, and, for the most part, they are brilliant. Two chapters, The War Room and How to Beat the Democrats, should be very influential upon politicians and the average reader. He preaches tactics and strategies that conservatives must hear and internalize. Important points are that politics are emotional and they should always be about hope. Republicans would be wise to learn from the words of this master. Ten more Horowitz's and the country would be in a much better place. He speaks his mind in beautiful prose and you'll turn these pages quickly. This is a highly recommended choice, indeed.
Solution:
Positive
