"Conservatives need to stop playing by the rules set by the left. With creativity and a little innovation, we can redefine the debate on our terms."

Writes Scott Walker, in his new book, which, we are told, criticizes Mitt Romney.

Walker writes that Republicans in 2012 didn't run on their principles, didn't criticize Obama enough and did a "lousy job of presenting a positive vision of free market solutions to our nation's problems in a way that is relevant to people's lives."

The book — "Unintimidated" — won't be out for another month, but you can pre-order it here.
