Kerry's credibility

With so many people uncharitably and inaccurately screaming that "Bush lied," it seems reasonable to ask questions about the truthfulness of M. Kerry. This is especially the case since Kerry has made such a point of emphasizing the necessity of truthfulness and transparency in a President. And since that is the case... doesn't Kerry have some explaining to do about the conflicts between his accounts of his military records and those of others?

If Kerry is telling the truth, and they are lying, we need to know that, too. But it's the height of hypocrisy to continue to bluster about President Bush's National Guard record months after the accusations that he was AWOL were conclusively proven false, while acting as if similar questions about Kerry's record are somehow off limits.
