Andy and Laura
Bush's closest confidants both tried to get Bush to dump Rumsfeld, and both failed, according to Woodward:
Card made his first attempt after Bush was reelected in November, 2004, arguing that the administration needed a fresh start and recommending that Bush replace Rumsfeld with former secretary of state James A. Baker III. Woodward writes that Bush considered the move, but was persuaded by Vice President Cheney and Karl Rove, his chief political adviser, that it would be seen as an expression of doubt about the course of the war and would expose Bush himself to criticism.
Card tried again around Thanksgiving, 2005, this time with the support of First Lady Laura Bush, who according to Woodward, felt that Rumsfeld's overbearing manner was damaging to her husband. Bush refused for a second time, and Card left the administration last March, convinced that Iraq would be compared to Vietnam and that history would record that no senior administration officials had raised their voices in opposition to the conduct of the war.
When even Andy Card knows they're headed for disaster, you know it's true.
