I could see the ad being very effective. But it also tosses a big softball to Hillary Clinton, who will speak to a national audience on Tuesday. The risk to the Republicans can be summarized in five words: "Shame on You, John McCain". A finger-wagging, how-dare-you moment by either of the Clintons at the convention -- but especially Hillary -- could be both effective and therapeutic, especially when coupled with a reminder that McCain voted against measures like SCHIP (and voted to impeach her husband).
