I don't think the solution to this is attacking the credibility of anyone. Attacking Kerry, Webb, or Bush for that matter gets us no where.
I say we save the political mudslinging for the months leading up to the election. This country needs to entertain ALL ideas and strategies for 'winning' in Iraq and 'defeating' terrorism; from those on the left and the right. It doesn't matter where the hell good ideas come from, so long as we recognize and employ them.
No doubts about it, we're in a shitty situation. All I am saying, is that amping it up and stepping forward seems a hell of a lot more promising (in the long term) than backing out; at least at this given point in time.
If anyone wants to jump in and lay down a logical argument as to how pulling away is a good idea in any way, manner, shape, or form, please do so.
