But pundits were astounded to see 2008 Vice Presidential candidate Sarah Palin appear on Fox News on Sunday to endorse the former Republican House Speaker: 'If for no other reason, rage against the machine, vote for Newt; annoy a liberal, vote Newt.

And her unexpected challenge might yet have an impact. A recent poll shaved Romney's lead down to just five points and another suggested his front-runner's position was ebbing.
