17 investigations over 35 years, all conducted by hostile Republican Committes, or by the FBI at the behest of Republicans, a 6 1/2 year Special Counsel's investigation, and endless harassment by Judicial Watch. Not a scrap evidence, a single witness, not one charge other than a lie about a blow job. Ken Starr jailed Katherine McDougall for an entire year for her refusal to implicate Clinton to the Grand Jury. She said she had nothing to give them, or she would have taken the "Get out of jail free card" and flipped. Both Ken Starr and James Comey offered immunity to a lot of people to get them to flip on the Clintons, and well many took immunity to protect themselves, but nobody gave investigators anything that would implicate either Bill or Hillary.
There's an old expression: "Three can keep a secret, if two of them are dead". We saw this with Richard Nixon. Someone always gets a conscience, or remembers their oath to uphold the Constitution and grows the spine. That's why conspiracy theories that Sandy Hook was a hoax perpetrated by crisis actors is just so laughable. It would take hundreds of people to pull of such a hoax, and the idea that no one of these hundreds of people would ever reveal the secret is laughable. There's always a Papadopolous who gets drunk and tells the wrong guy in a bar about the whole deal.
The last reason why I don't think the Clintons are guilty of anything, besides the total lack of evidence or witnesses, is that everything they have ever done has been investigated, and usually multiple times. If Hillary had jaywalked, the Republicans would have locked her up. If I knew that everything I ever did would be subject to FBI Investigation, I wouldn't breathe the wrong way, much less engage in bribery, corruption, and pay for play in the public realm.
Trump isn't that smart.
