Last Tuesday, presumptive Democratic nominee Hillary Clinton got an almost-certain reprieve from the potential criminal prosecution that's been hanging over her head since the news broke about her using a private email server for official business when she was secretary of state. FBI Director James Comey, in a carefully worded statement, announced the bureau's view that "no charges are appropriate in this case." Absent the slim chance that Justice Department prosecutors will reject the FBI recommendation, Clinton is home free, criminal jeopardy-wise.

But was that the end of the Clinton email scandal? Nope.

Clinton's political opponents and enemies won't let the controversy go. And Comey's statement has given them no reason to do so. Instead, it virtually guarantees that the Clinton email affair will take up residence in the land of zombie scandals that hover between life and death because they never come to a definitive conclusion.
