South Carolina And CNN: The Undecideds

CNN had 17 undecided South Carolina voters rating the candidates throughout the debate. At the end, according to CNN, they thought Edwards had won the debate but "half" of them were going to vote for Obama because they felt he had the better chance of winning the nomination.

Don't they understand that if everyone who felt that way actually voted for Edwards, he might have a realistic chance at winning? This is an amazing and historic primary campaign, but also a supremely frustrating one.
