You, being someone who cares about the reasons behind the vote, should probably not use Hillary’s Iraq vote against her, since her reasoning behind the vote is well documented and clearly shows she was not actually in favor of the war, but instead voted yes with extreme reservations.
Well, that’s sort of my larger point. A mere checkbox on a policy or a vote doesn’t tell the entire story behind the vote. That vote was weaponized against her, as you well know, by the Sanders people.
