Jenga is a family favorite that the Romneys have been known to play when they gather over holidays.

Tweets from the people closest to Romney behind the scenes show him "getting his game face on," in son Craig's words, with the help of his wife, Ann.

Jackson snapped a shot of the Romneys holding hands in the car  an hour before the debate as the motorcade headed to the University of Denver, where the debate is being staged.

Jackson was tweeting up until minutes before Romney headed out on stage.
