Flip-Flop vs. Steadfastly wrong

I am watching ABC New's This Week and am growing tired of George S. making John Edwards out to be a flip-flopper like the Republicans did to Kerry in 2004. What is the alternative to admitting a previous decision, which may not have been based on all the information in existence, because all such information was not available, was not the right one? I guess the alternative is to be "the Decider" and to never admit you have made a mistake and to pig-headedly continue in the direction to which the mistake lead.
