Why does the innuendo about Clark outweigh the innuendo about Dubya?

I'd like the mudslingers to tell my why Clark's early retirement is more important than Bush's "AWOL for a year" record.

Clark is a wounded decorated combat veteran. He accomplished what his superiors had said was too risky to try, i.e. take on the Serbs and win without losing a man.

I can understand disagreeing with his policies, but the hypocritical slander is just beyond me.
