Would you want a leftist trying to exploit a tragedy? No more than the real ones do i imagin. They would get "killed" in public opinion, and they probably know that.
i am against the war as it is being planned. We are using a "sledge hammer" when we need a "small hatchet". There is no need for a full scale invasion of Iraq. You really think their military wants some more of what they got the last time? They're not stupid, even if their leader is. If we want those WMD sites gone, they can disappear tomorrow...we know where they are. We can close the entire Iraqui border, and not let so much as a jackle cross it, and there is not a thing Saddam Halfwit can do about it. One fuel-air bomb on those WMD sites, and they don't exist any more...Who could stop us?
Getting back to point though, look for the Left to exploit, but not in a "directly detrimental" fashion. Some of those old Leftists were around in the Glory Days of the Space Programme, they have their own emotional attachments to it.
