The media didn't make this clear although the AP sent it out: "No Alabama Air National Guard records have surfaced showing Bush did any duty there. Former commanders and other members of the 187th in 1972 and 1973 say they don't remember ever seeing Bush there"
Didn't you notice the supposedly "liberal" media didn't make this clear to the public? As far as the memos, the content did check out. Many of the claims about why the memoes were fake turned out to be wrong, including claims that the "th" superscript did not exist. The bottom line was Bush didn't show up when he did and others confirm that the content of the memoes is acurate.
You seem to think the media is "liberal". Here are two examples that should make you rethink your simplistic world view.
The "liberal" media Violating International Law refused to report the war was illegal nd they no fly zones played along with the "no fly zones" there-is-big-problem don't assume the media "would tell you" about things like this CBS Bush documents Media Should Have Probed Bigger Questions About Bush's Record
This link goes into detail: mediamatters.org "Media Matters has extensively documented the substantial and uncontested evidence that Bush didn't show up for duty when he was supposed to, that he skipped a required physical for as-yet-unexplained reasons, that he was grounded from flying, and that he mysteriously received an honorable discharge anyway."
