Greg Palast writes: Newly unearthed records reveal that, in 2004, when Americans were in the midst of a brutal electoral battle over whether to reelect a president posing as a war hero, a commanding US reporter, Dan Rather, went AWOL. Just three months before the election, Rather had a story that might have changed the outcome of that razor-close race. We now know that Dan cut a back-room deal to shut his mouth, grab his ankles, and let his network retract a story he knew to be absolutely true. In September 2004 when Rather cowered, Bush was riding high in the polls. Now, with Bush’s approval ratings are below smallpox, Rather has come out of hiding to shoot at the lame duck. Thanks, Dan. It began on September 8, 2004, when Rather, on CBS, ran a story that Daddy Bush Senior had, in 1968, put in the fix to get his baby George out of the Vietnam War and into the Texas Air National Guard. Little George then rode out the war defending Houston from Viet Cong attack. The story is stone-cold
