Karl Rove biographer: 'This is the end of the Bush presidency'

Wayne Slater, author of The Architect: Karl Rove and the Master Plan for Absolute Power, joined CNN on Monday to deliver what was, in effect, a political obituary on both Rove and the Bush administration.

"He can be called ... someone who was extraordinarily successful in the politics of -- politics," said Slater. "He is brilliant as a political strategist, and yet at the end, we've seen this colossal failure by the Bush administration, this collapse, and he has to bear some responsibility for that as well."
