If I were Kerry, I would gin up a one minute ad campaign starring John McCain (SBVFT ad is "dishonorable and dishonest") and GWB (Kerry served admirably and he should be pround of his service) and list my military decorations. I would then show it in the battleground states opposite the SBVFT ads.
McCain is the Bush campaign chairman for Arizona. He better not show up in any Kerry campaign ads. That would be way out of line if you ask me.
An ad of the sort you envision could be made from just about anything somebody has said at various times. Hell, clever editing could probably produce a ransom note from what W said.
And Bush, by making today's comments, give Kerry half the ammo to do just that.
