From Matthew Iglesias:
"Chris Bowers notes that 59 percent of Democrats believe that John Edwards is proposing to withdraw all US forces from Iraq within nine months. 71 percent believe that Barack Obama is proposing to do this. And 76 (!) percent believe Hillary Clinton is proposing to do so. Needless to say, none of them are, in fact, proposing anything of the sort--though I wish they would."
So, if all three candidates are wary of calling for troop withdrawal because they fear public disapproval, but the public believes that they are calling for troop withdrawal -- then the candidates might as well call for troop withdrawal. Especially as this is what voters actually want, and, even more importantly in this particular case, because there really are no good reasons to stay in Iraq, not even reasons prompted by the best possible intentions.
