wanted to get in a dig on Christie (and assuming both would be in contention after New Hampshire), an ad could be created showing two people in the front seat of a car.

They're in New Jersey. Traffic is backed up.

One asks the other if she's decided on whom to vote in the Republican primary. The other says "Not yet. How about you?"

"Not really. I still need to think it over. What is it with this damn traffic anyway?"

(the camera pans out, showing several lanes of traffic jammed. Horns are honking. A few people are standing outside their vehicles looking pissed off.)

The two in the front seat continue to talk about the primary.

At the end of the ad, the camera pans up, showing vivid orange cones closing off lanes to the George Washington Bridge, then swings back to show the traffic backed up. No dialogue, just car horns honking.
