Serving your country in a time of need is a good and noble thing to do, but walking with your eyes open into service under a CinC who will send you off to be killed without a second thought and who will not support you either with money or with true force of will takes a bigger set than I've got.
I wouldn't mind being sent to a war to possibly die under the command of a CinC who actually understood what was going on and was willing to do what it took to support me and make my death mean something, but you know that the first thing Kerry will do when and if he takes over is start planning the exit from iraq. He will pull a "Vietnamization" type plan and withdraw US troops FAST and allow Iraq to backslide. It'll end up under the control of Iran, and that will be a disaster.
A clear measure of the man President Bush is, is the fact that despite sliding poll numbers, he is staying the course in Iraq. He may lose the election over Iraq, but he knows it is the right thing to do for the US, for the middle east and most of all, for Iraq, so he's getting it done regardless of the personal political costs. That's a CinC I can stand behind and fight under.
What the American soldier wants is not safety, but a President who will keep faith with him (or her) and make their service meaningful. President GW Bush does that, John F*ckface Kerry will not, and they know it.
