Closing in on the first and very important primary elections in Iowa and New Hampshire, Cain's departure will allow
Gingrich the opportunity to cement his status as the "Not Romney" candidate that the more hard-line Republican voters have been auditioning candidates for since the summer. Many voters have been cringing at the thought of voting for the moderate Romney, especially surrounding his support of a health care mandate that on some level is similar to the current administration's.
Gingrich just happened to be the last one up of the alternative candidates, as he's watched Bachmann, Perry and Cain fall by the wayside. It's hard to imagine many of Cain's supporters heading towards the Romney camp, and indeed many of them have already defected towards Gingrich's camp as allegations of infidelity and inappropriate relations hounded Cain's campaign. Indeed, this may be the surge that Gingrich needs to stake his claim once and for all as the challenger to Barack Obama.
