The House Democrats are probably hitting themselves after they made the mistake of releasing a transcript that revealed that Sidney Blumenthal had received a lot of money for serving as a consultant. This will create another burden for Clinton, just as she's trying to escape her email scandal - now we know the special treatment that her friends get.
Clinton's campaign is already plagued with suspicion from certain members of the American public. This new information is going to make them even more suspicious. This is especially problematic because many of these votors are either undecided or are very committed supporters of Bernie Sanders and she and her campaign need to win them over.
House Democrats mistakenly released a transcript showing Clinton friend Sidney Blumenthal received a large amount for consulting. This should not in any way hurt Clinton's campaign for presidency. The media and politician's are always trying to find ways of hurting the opposition, but they forget that bad things happen in the world every day. This will soon be forgotten
No, the transcript mistakenly released by House Democrats showing Sidney Blumenthal received large amounts for consulting will not hurt Clinton's campaign much. Republicans may point to it as an example of her big-money interests, but it will quickly blow over. In this election, voters seem to care very little about this type of issue.
