"Playbook 2012: The Right Fights Back:" Was Chris Christie smart not to run?

The Republican candidates haven't even gotten through the Iowa caucuses yet and already the first reflective book on the 2012 campaign is out.

In the newly released e-book "Playbook 2012: The Right Fights Back," Politico's Mike Allen takes a closer look at the men and women still in the race, and the causalities, drawing the conclusion that it's hard to run for president.

"I call Governor Chris Christie the only smart one in this whole process," Allen told CBS News political director John Dickerson in an interview on CBSNews.com's webcast "Hotsheet Live."

"When the money people were looking at Rick Perry fading, and coming to Chris Christie, whispering in his ear, 'this is an opportunity for you,' he said 'no, I look to Rick Perry and see the danger for me.'"

Journalist and author Evan Thomas co-authored "Playbook 2012: The Right Fights Back" with Allen.
