They don't have to go. According to them everyone knows Iraq is a mess, because they can see it on TV.
I see a good commercial in the making:
Kerry: "Iraq is a quagmire"...
First person who's actually been there tells first success story.
Kerry: "you can see it on TV"
Another person tells of another success.
Kerry: "we're doomed"
Recording of Iraqi Interim President (Prime minister, I can't remember) from his speech in front of congress, tabulating successes.
Voice over: "Who would you believe, Senator Kerry who's never been to Iraq or these people who have?"
