Saudi Arabia is the wellspring of radical Islam, its primary source of sustenance and inspiration. Yet, since September 11, the Bush administration has consistently ducked the truth about Riyadh's role in nurturing terrorism -- and concealed the truth as well. Given the many business and personal ties binding the president, his family and his associates to the House of Saud, George W. Bush's see-no-evildoer attitude toward the Saudis is a vulnerability just begging to be exploited by the Democrats. And they need to do so if they hope to recapture the presidency next year.
