In sports there's something called a challenge trade -- when two teams trade underperforming players at the same position. Romney and Santorum are engaged in something of a challenge air war. Romney err, Restore our Future is up attacking Santorum, trying to undermine Santorum's conservative street cred. http://www.youtube.com/watch?v=xziumBt0Tls
The ad is pretty mediocre, basically a message delivery device without much creativity. But the point is to try and muddy the waters and subvert Santorum's message that he's the real conservative -- would the "right" choice really vote <gasp> to raise the debt limit? If Romney's not a man of the people, then neither is Santorum the "Ultimate washington insider." If I was grading the ad, I would probably say it's about a C or C+ if I was feeling generous. There's nothing really wrong about it,but there's nothing compelling or interesting. Actually not sure why they include the Romney stuff, it's not really catchy
Santorum on the other hand is running a pretty interesting ad with an interesting strategy behind it. It's a gimmick ad, but the gimmick works because it reinforces the message. "Rombo" is on the lose shooting mud at Santorum. It's actually a pretty clever concept, and they certainly go all the way with it, down to an actor who looks like Romney. I like the concept the execution is good, but not great, but I think the strategy behind it is just as clever.
Rombo also is subtlety subversive -- Romney isn't the tough conservative he plays on TV (Rambo), but some kind of phony "Rombo" shooting a mud in a white shirt and tie. It's a slight jab, but the subtext might be more effective at capturing the anti-Romney malaise that Republican primary voters are feeling than the text.
Santorum can't compete with Romney's cash advantage (I saw it as at least 3:1). This ad is trying to functionally dislocate Romney's advantage -- it's not an unusual strategy, but well played in this case. The hope is to remind voters of Romney's negatives every time you see a Romney ad attacking Santorum. While, I'm not a fan of the ultimatum approach at the end, I still think given the execution of the ad it could be effective in helping to blunt Romney's advantage.
By wrapping the message around such an entertaining and off-beat concept, Santorum might be able to poison Romney's negative ads.
The easy winner this round is Santorum. The only question is can Santorum continue to move and out flank Romney.
