As I said before, quid pro quo needs to be demonstrated, particularly when Secretary Clinton didn't control who could and could not donate to the Clinton Foundation. A maybe argument isn't much of an argument at all. In addition, President Obama received Wall Street campaign money, but that didn't change his policy positions, and he still signed into law Dodd-Frank. As Donald Trump once said in an interview in an attempt to explain his previous political donations to the Clintons and other Democrats, donors tend to cover their bases and donate to a wide range of candidates.
In summary, a candidate cannot be blamed for the donations he or she receives, whether the donations are political or to a charity one has no control over.
