On the heels of many investigations into her conduct as Secretary of State, the current FBI probe again demonstrates Clinton's inability or unwillingness to play within the rules. We don't yet know how much sensitive classified information has been leaked or stolen, whether Clinton intended to or not. Really, she's a high-profile lawyer, and she should know better.
While this investigation will be spun to make Clinton look like a criminal by her opponents, I don't think it's enough alone to cost her the general election win when she has so much else on her side. However, her campaign will have to figure out a way to address this.
Hillary Clinton has always been able to stand many political storms and controversies. She has been in the public eye for so long, that most people already know everything about her. Many people hate her and would never voter for her, but the rest of the population has to decide if this is a deal break when Donald Trump is the alternative.
This whole idea that Hillary Clinton is going to be criminally prosecuted is absolutely ludicrous. She admitted that she made a mistake, but there has yet to be any proof that she intentionally broke any rules or caused danger to our country. This whole thing is about nothing more than politics, and soon will fade away.
