^ He himself said it was bad politics not to go after about it, so whatever your opinion, sanders does not share it.
He should have hit her with both barrels, now people wonder why he is there, Shillary's sliminess is her Achilles heel, he has to highlight it if he wants people to take him seriously as a candidate, it also brings into question her (lack of) judgement.
Looks like he has finally realised that and he is starting to get aggressive. He missed a golden opportunity.
His poll numbers have dipped and shill's have risen, so he could do worse than me ie you and the other bb.
Even if he is too gentlemanly to use such tactics, it was dumb to make it so that none of the other candidates could use that topic.
