You're mistaken. Bush DID very well in his presentation of personal accounts. Congress already has them, he said, so what is good for them should also be good for others.
I suppose "persuasive" means as in "persuade" as opposed to meaning "correct," come to think of it. Thus, I would have to listen to Bush to judge. Maybe if he was, then he was just effective in selling the incorrect ala a snake oil salesman. I will listen to the repeats on CSPAN in any event.
