The public secret

Call me crazy but sometimes these speeches by Bush seem somewhat redundant.
Reuters reports: 'Unswayed by doubts among Americans, President George W. Bush plans to announce on Wednesday that he will send about 20,000 more U.S. troops to Iraq as part of a long-delayed new plan for the unpopular war.'
CNN says, 'In the speech, set for 9 p.m. ET, Bush will announce a plan to send about 20,000 more troops to Iraq in an effort to pacify Baghdad, according to an unnamed U.S. official who spoke to CNN on Tuesday.'
While the BBC tells us, 'The president is expected to bolster the US presence in the country by sending at least 20,000 extra troops to Baghdad and the restive Anbar province.'
Um.. so why are we having this speech? Isn't this news bad enough without Dubya telling it to us yet again? Or is it for the benefit of those three staunch supporters of Bush who don't believe anything unless they've seen him say it personally?
