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.
I think Bush chose today for a formal Press Conference because today the Iraqi government formed its 265 member government (congress/parliamnent)...He follows the trend of supporting that fledging government on big occasions! Good man, our President! STAYING THE COURSE (see beeGees "staying alive" for reference)
