Barack's Decision: How Do I Deal with a Pitbull?

Palin, in her campaign debut, introduced herself as a "pitbull with lipstick." So my question is, how does the Obama campaign plan to respond, now that she has shown us that she wasn't just being clever or entertaining. At the dog park I go to, when a dog gets vicious, you go to the owner. In this case, that would be McCain. So will Obama, as Ed Schultz suggests, challenge him on this during Tuesday's debate?
