Here's a real challenge. The Bush cabinet?

You are indeed mistaken.

Paul ONeil was forced to resign as Secretary of the Treasury in 2002 for daring to say that the Bush tax cuts would lead to deficits of up to half a trillion dollars.

Mel Martinez resigned in 2003 as Secretary of Housing to run in the 2004 senate elections.

Christine Whitman was forced to resign as Administrator of the EPA for daring to suggest to Dick Cheney that the EPA should be interested in environmental, not corporate, protection.

Mitch Daniels left his position as Director of the office of Budget and Management in 2003 after clashing with the administration over budget deficits.

Only four members of Bush's cabinet have survived the entire administration to date. Condi Rice served as National Security Advisor and then Secretary of State. Elaine Chao has been Secretary of Labor since the president's first term began. John Walters has served all 7 years at the helm of the Office of National Drug Control Policy as has Robert Mueller at the FBI.

Yes, the info is publicly available.

The link below list the cabinet members for every President.

You'll probally be surprised to learn, that Bush hasn't had more Cabinet members than the other Presidents have had.
