This video should be aired by the McCain campaign. Although how you would handle the “approve of this message” blip at the end might be problematic.
I started thinking the exact same thing while watching. Here are some ideas that came to mind:
“... I’m John McCain and am required by law to say I approve of this message, even thought I don’t.”
or
“..I’m John McCain, and that stupid Feingold law requires me to lie and say, “I approve of this message.”
