The sudden, high-profile defection of Michele Bachmann’s Iowa campaign cochair to Ron Paul certainly raises viability questions about the Minnesota congresswoman’s presidential bid.

Sorenson’s explanation for his departure suggested that he views Paul, who is now an Iowa frontrunner, as the most conservative candidate with a shot at winning the nomination.
