Of course the Obama administration was not going to prosecute Hillary Clinton
When considering the recommendation of Federal Bureau of Investigation director James B. Comey against a prosecution of Hillary Clinton over the e-mail scandal, bear two things in mind.
First, for all their pretensions about the insulation of law enforcement from politics, the FBI and the Department of Justice are agents of the executive branch. As a matter of constitutional law, the power they are delegated to exercise is the president’s, and they wield it at his pleasure. The highly ambitious men and women in coveted executive-branch leadership posts always have the option of honorably resigning if they find the president’s bidding too unsavory to do; but if they remain, they do what is expected of them.
