Americans love this line:
"Who you gonna believe? Me or your lyin' eyes?"
Kerry/Edwards need something to synthesize their barrage of arguments--on the state of Iraq, on job creation, on the deficit, on who got the tax cuts, etc. etc., etc--which point out that what the Administration says is plainly at odds with what they've done and what's out there on TV screens.
Kerry: "America, this President keeps telling you, 'Who you gonna believe, me or your lyin' eyes?'"
