Only by the thinnest of possible veils. The motives for this move appear to be overly transparent, and, well, Obama has promised / claimed to have the most transparent government in history, but I don't think he meant transparent motives.
I'd say that some voters would claim this and others would claim what you just outlined.
The other possibility would be that the most damming of the FBI investigation evidence would be leaked, perhaps to WikiLeaks?
Regardless, should the Hillary presidency come to pass, it'll be a disaster. All of these pre-election scandals, her long standing track record of corruption, bad decisions, and bad judgement, and her very high negatives, they all have the impact of watering down, if not eliminating, her political capital, political capital that presidents use to actually govern and accomplish anything. So the course is already pretty much set that hers will be a disastrous presidency, ineffectual in the extreme, due to this lack of political capital. I doubt that she'd be able to overcome that.
Anyone who imagines federal prosecutions can't be rigged should read some time about the
Amerasia scandal of 1944-45. A U.S. foreign service officer had been living in Chungking with two housemates we now know were Soviet agents, all three of them doing all they could to influence U.S. policy against Chiang Kai-Shek and in favor of Mao Tse-Tung. When this FSO returned to the U.S., he plugged into a network of Communists and Communist sympathizers in both private institutions and various federal agencies who wanted to advance the interests of the Chinese Reds. Several of these federal officials were also Soviet agents.
Through contacts in this network, the FSO was introduced to a well-off Communist who published an obscure academic journal on the Far East called
Amerasia. The FBI already had this man under surveillance because of other suspicious activity by him, and it recorded his meetings with the FSO. It also searched his offices soon after those meetings, where FBI agents photographed about fifty secret military documents as well as photographic equipment of the type then used to copy documents.
FBI agents then observed the head of the Communist Party USA and a senior Red Chinese official enter the publisher's home and remain there several hours, during which time they obviously could have been given copies of the documents and been told other relevant information. Meantime, the FSO had been busy making the social rounds in New York with the publisher's assistant, a young woman whose uncle was a wealthy Buffalo lawyer, and several of her fellow Reds, one of them now known to be a Soviet agent.
The FBI took its evidence of all this to Justice Dept. prosecutors, who agreed it would support prosecutions for serious crimes. The FBI then arrested the FSO, the publisher, his assistant, and three other people. And that's when the fix began. There is no doubt about it, because President Truman, for entirely unrelated reasons, had an influential New Deal official who was at the center of it under surveillance. So there are this official, senior Justice Dept. officials--even the Attorney General himself--directly revealing, in phone conversations, the skulduggery they were engaging in to prevent a grand jury from indicting the FSO and his comrades.
A private lawyer, Hitchcock, was called in to manage the thing, and he worked with another lawyer with connections to the Attorney General that the assistant publisher's uncle had gotten to represent her. Among them, they made sure the grand jury never heard the most damning evidence. The documents were misleadingly portrayed as not involving military secrets, and their transmission portrayed as nothing more than the ill-advised act of an over-eager young diplomat who was just trying to help a fellow China enthusiast by sharing his firsthand knowledge of what was going on over there. In the end, the grand jury no-billed the FSO, another man, and the assistant publisher of
Amerasis--and Hitchcock later was given a plum job in the uncle's Buffalo law firm.
FBI Director Hoover was flabbergasted, because he knew the evidence in detail. Several years later, when under pressure from Sen. Joe McCarthy and others the
Amerasia coverup threatened to be made public and become a full-blown scandal, Hoover panicked the administration by implying at several points that he might tell everything he knew. But in the end he did not feel he could go that far, and so the original lies were covered up with even more lies, and the furor quietly died away.
