The original question the FBI investigation of the Trump campaign was to answer was a simple one: Did he do it?

Did Trump, or officials with his knowledge, collude with Vladimir Putin’s Russia to hack the emails of John Podesta and the DNC, and leak the contents to damage Hillary Clinton and elect Donald Trump?

A year and a half into the investigation, and, still, no “collusion” has been found. Yet the investigation goes on, at the demand of the never-Trump media and Beltway establishment.

Hence, and understandably, suspicions have arisen.

Are the investigators after the truth, or are they after Trump?

Consider an explanation for what is going down here:

That, from the outset, Director James Comey and an FBI camarilla were determined to stop Trump and elect Hillary Clinton. Having failed, they conspired to break Trump’s presidency, overturn his mandate and bring him down.

Essential to any such project was first to block any indictment of Hillary for transmitting national security secrets over her private email server.

On July 5, 2016, Comey stepped before a stunned press corps to declare that, given the evidence gathered by the FBI, “no reasonable prosecutor” would indict Clinton. Therefore, that was the course he, Comey, was recommending.

Attorney General Loretta Lynch, compromised by her infamous 35-minute tarmac meeting with Bill Clinton seconded Comey’s decision.

And so Hillary walked. Why is this suspicious?

First, whether or not to indict was a decision that belonged to the Department of Justice, not Jim Comey or the FBI. His pre-emption of Justice Department authority was astonishing.

Second, while Comey said in his statement that Hillary had been “extremely careless” with security secrets, in his first draft, Clinton was declared guilty of “gross negligence” — the precise language in the statute to justify indictment.

Who talked Comey into softening the language to look less than criminal? One man was FBI Deputy Director Andrew McCabe, whose wife, Jill, a Virginia state senate candidate, received a munificent PAC contribution of $474,000 from Clinton family friend and big bundler Terry McAuliffe.

Also, it appears Comey began drafting his exoneration statement of Hillary before the FBI had even interviewed her. And when the FBI did, Hillary was permitted to have her lawyers present.

One need not be a conspiracy nut to conclude the fix was in, and a pass for Hillary wired from the get-go.

If Special Counsel Robert Mueller cannot find any Trump collusion with the Kremlin to tilt the outcome of the 2016 election, his investigators might have another look at the Clinton campaign.

For there a Russian connection has been established.

Kremlin agents fabricated, faked, forged, or found the dirt on Trump that was passed to ex-British MI6 spy Christopher Steele, and wound up in his “dirty dossier” that was distributed to the mainstream media and the FBI to torpedo Trump.

Has the Mueller probe been so contaminated by anti-Trump bias and reliance on Kremlin fabrications that any indictment it brings will be suspect?

Mueller is left to rely upon a passel of prosecutors whose common denominator appears to be that they loathe Trump and made contributions to Hillary.

Attorney General Bobby Kennedy had his “Get Hoffa Squad” to take down Teamsters boss Jimmy Hoffa. J. Edgar Hoover had his vendetta against Dr. Martin Luther King.

Is history repeating itself — with the designated target of an elite FBI cabal being the President of the United States?
