Alberto is the Key

Here is an interesting piece from Salon, focusing on the reasons why Alberto Gonzales has not been fired by Bush, even with his mendacity laid bare.

Money quote: "Following the notion of the unitary executive, in which the departments and agencies have no independent existence under the president, the White House has relentlessly politicized them. Callow political appointees dictate to scientists, censoring or altering their conclusions. Career staff professionals are forced to attend indoctrination sessions on the political strategies of the Republican Party in campaigns and elections. And U.S. attorneys, supposedly impartial prosecutors representing the Department of Justice in the states, are purged if they deviate in any way from the White House's political line."
