I'm not so sure. Apparently Bush and his loyal supporters want to watch her cook a little while longer. Until she's charred, evidently.
I still predict she'll be confirmed. Not a single Republican Senator has come out against her. Moreover, supporters of the war who are potential opponents of Miers, will circle the wagons for Bush if indictments come down this week....thus helping Miers.
She didn't return her questionnaire by the 6pm deadline today. Maybe a withdrawal is imminent and she didn't want to waste her time.
