From the latest Zogby poll on the President's popularity;
"In a sign of just how severe the damage to the President’s standing caused by Katrina is, the Zogby America survey finds that, despite his re-election last fall, President Bush would lose to every modern president since Jimmy Carter, the one-term Democrat who left office amid record unpopularity and a presidency rated, at the time, dismally.
He would also lose to his own father, who left office amid an economic recession triggered, in part, by a devastating hurricane."
Interestingly enough, Bush would still beat John Kerry. Which may say more about Kerry's fantastic lack of charisma than anything else.
