Petraeus VS. Kerry - Double Standard?

[buckymcnix]

Ok well all this flap about Petraeus/Betray Us.

The politicians on the right who are now saying that it is so wrong to insinuate/say these things about Petraeus because it is unamerican to call into question a decorated military man's honor. Yet, when Kerry ran for prez, they slandered him up and down, even to go as far as to say he shot a vietnamese child IN THE BACK as he was running from kerry. They wore little purple heart band-aids to mock his war injuries at the republican convention.

Is there something i am missing that makes the circumstances different?
