Steven Taylor explains the importance of Iowa and New Hampshire:
[T]here is no example of an eventual nominees utterly failing in IA and NH (defined as third or worse in both) and then going on to success. Perry, Bachmann, and Gingrich all appear destined to achieve that level of failure in both contests. As such, focusing on SC is a longshot strategy.
Yesterday, Jennifer Rubin likewise dismissed Perry's and Gingrich's plans to make a stand in South Carolina.
