I don't see any way that the Clinton pardons can fail to be a problem for Hillary Clinton's campaign.
More here. Lots, lots more, including the hundreds of thousands Bill Clinton is raking in for giving post-presidential speeches. Consider the fact that anyone who wants to curry favor with Hillary Clinton can now pay cash directly to Bill Clinton. Combine that with the Clinton track record on calculated political pardons for wrongdoers, and we're looking at a "perfect storm."
