Tonight, the latest edition of Survivor: Republican Primary moves once again to Fox News Channel, which will televise and moderate tonight’s debate in South Carolina.  Thanks to the withdrawal of Jon Huntsman, the stage will get cozier and perhaps the responses lengthier in the game-show format used in almost all of the media debates over the last several months.  This won’t be the final debate before Saturday’s primary in the Palmetto State; CNN will air one on Thursday evening, presumably with the same number of candidates, although at this rate … who knows?

When Michele Bachmann withdrew after the Iowa caucus, her absence arguably changed the dynamic of the debates.  Bachmann had consistently attacked the other Republicans on stage, sometimes very effectively, and particularly Rick Perry and Newt Gingrich.  Huntsman’s withdrawal will not change the debate dynamic much, if at all, unless Fox (and then CNN) allow for longer responses rather than more questions.  It also could allow each candidate to answer every question, something that was impossible with seven, eight, and nine candidates on stage at the same time.  The absence of Huntsman might mean fewer questions on China in particular, although Paul’s presence guarantees that foreign policy will remain a key debate topic throughout the rest of the primary debates.  Otherwise, it’s going to basically be a repeat of the last several debates, and the big question will be whether one of Mitt Romney’s opponents can find a way to (a) trip him up, or (b) find a way to distinguish himself as the clear alternative to a Romney nomination.

Here’s how I see the strategy for tonight’s final five:
