So Sen. Saxby Chambliss has announced that he will not seek re-election to the U.S. Senate in 2014, citing “frustration” with partisan politics in Washington. I find that more than a little ironic. Chambliss was able to avoid military service during the Vietnam War through student and medical deferments and yet viciously attacked then-Sen. Max Cleland during the 2002 campaign as unpatriotic, despite the fact that Cleland had served with distinction in Vietnam and lost three limbs there.
