Edward simply said flat out "I was wrong." Why can't Hillary do the same? She's just a pro-war right-wing pandering whore.
Because, she wasn't "wrong." At the time she casted her vote, based on the information she had at the time and in her best judgement for the good of the nation, her decision was sound. Edwards, on the other hand, is the one pandering to the anti-war crowd. That is why I get so annoyed with these "If I knew back then what I know now, I would have voted no" folk. Have a spine and defend your actions, and then explain how in the future if the said event occurs again, what you would do to ensure you make the correct decision.
