The debate marathon continues Tuesday night, as Republican candidates take the state in Nevada. All eyes will be on Herman Cain again, as he tries to put his “Pizza Jam” behind him and establish his seriousness as a candidate. There may also, however, be some tension as several candidates have pledged to boycott Nevada’s early January 14 caucuses. Jon Huntsman has said already he’ll skip the debate—although that may have more to do with his lagging finances. The rest of the candidates, except for Mitt Romney, Rick Perry, and Ron Paul, have said they will or are considering boycotting the Nevada caucuses.
