Going by the exit poll data in various sections, south carolina is overwhelmingly breaking for Newt. Ultimate face palm. If the republicans want to abandon their values, then so be it.
The campaign made its biggest mistake so far by going after SC.
Yes a winner can be called based on exit polls if the difference is significantly beyond the margin of error. It's called statistics.
Only 5% of voters think Ron Paul is most likely to defeat Obama. Liberal Newt - 48%.
Yuck.
If by going after you mean campaigning lightly, then yes. Not a lot of resources were placed there, from my understanding.
