May I suggest a response?
"Yes, I voted against the war. This was partly because I thought that diplomacy had not been exhausted, as it should be before the lives of American troops are put at risk. Also, it was partly because I was against giving a blank check to the first President Bush and his Secretary of Defense Dick Cheney to blow past Kuwait and invade Iraq. Thank God President Bush's father, unlike his son, had enough sense to not proceed to Baghdad."
Now we just have to deal with Biden's vote for the Second Gulf War.
