rick perry at 4. carl cameron in his home state, handover, new hampshire. good morning, carl. has perry talked about what he needs to do tonight? reporter: yes. in fact the texas governor has been fairly candid about his need to do a little more book work, study up a little bit, perhaps get himself a full night s rest. he did have a very aggressive campaign weekend but he essentially let this day be dedicated to exclusively prep for today s debate because there is so much riding on it. there will not be a national audience at dartmouth in new hampshire. it will be watched in new hampshire and iowa. the two lead off votes. perry hard to say that there couldn t be much more riding on this. if he doesn t reverse the trend in what a real plummet empty polls his ability to continue to compete while well-funded will be suspected by a lot of conservatives. mitt romney leading in iowa in some polls as well as new hampshire and nationally there will be tremendous amounts of criticism and
