President George W. Bush called him "the architect" of his reelection victory and he has been the president's chief strategist from the beginning. But Karl Rove is much more than a political guru, he is the single most powerful policy advisor in the White House. FRONTLINE and The Washington Post join forces to trace the political history and modus operandi of the man who has been on the inside of every political and policy decision of the Bush administration, including the current battles on Social Security, taxes, and tort reform. For Rove - observers say - enactment of the Bush agenda is a way to win the biggest prize of all: a permanent Republican majority.
