For a year, the big question of Russiagate has boiled down to this: Did Donald Trump’s campaign collude with the Russians in hacking the DNC?

And until last week, the answer was “no.”

As ex-CIA director Mike Morell said in March, “On the question of the Trump campaign conspiring with the Russians … there is smoke, but there is no fire, at all. … There’s no little campfire, there’s no little candle, there’s no spark.”

Well, last week, it appeared there had been a fire in Trump Tower. On June 9, 2016, Donald Trump Jr., Jared Kushner and Paul Manafort met with Russians — in anticipation of promised dirt on Hillary Clinton’s campaign.

While not a crime, this was a blunder. For Donald Jr. had long insisted there had been no collusion with the Russians. Caught in flagrante, he went full Pinocchio for four days.

And as the details of that June 9 meeting spilled out, Trump defenders were left with egg on their faces, while anti-Trump media were able to keep the spotlight laser-focused on where they want it — Russiagate.

This reality underscores a truth of our time. In the 19th century, power meant control of the means of production; today, power lies in control of the means of communication.

Who controls the media spotlight controls what people talk about and think about. And mainstream media are determined to keep that spotlight on Trump-Russia, and as far away as possible from their agenda — breaking the Trump presidency and bringing him down.

Just days into Trump’s presidency, a rifle-shot intel community leak of a December meeting between Trump national security adviser Gen. Michael Flynn and Russia’s ambassador forced the firing of Flynn.

An Oval Office meeting with the Russian foreign minister in which Trump disclosed that Israeli intelligence had ferreted out evidence that ISIS was developing computer bombs to explode on airliners was leaked. This alerted ISIS, damaged the president, and imperiled Israeli intelligence sources and methods.

Some of the leaks from national security and investigative agencies are felonies, not only violations of the leaker’s solemn oath to protect secrets, but of federal law.

Yet the press is happy to collude with these leakers and to pay them in the coin they seek.

Consider the original Russiagate offense.

Confidential emails of the DNC and John Podesta were hacked, i.e., stolen by Russian intelligence and given to WikiLeaks. And who was the third and indispensable party in this “Tinker to Evers to Chance” double-play combination?

The media itself. While deploring Russian hacking as an “act of war” against “our democracy,” the media published the fruits of the hacking.

If the media believed Russian hacking was a crime against our democracy, why did they publish the fruits of that crime?

Not only do our Beltway media traffic in stolen secrets and stolen goods, but the knowledge that they will publish secrets and protect those who leak them is an incentive for bureaucratic disloyalty and criminality.

Our mainstream media are like the fellow who avoids the risk of stealing cars, but wants to fence them once stolen and repainted.

Bottom line: Trump is facing a stacked deck.

People inside the executive branch are daily providing fresh meat to feed the scandal. Anti-Trump media are transfixed by it. It is the Watergate of their generation. The Pulitzers are calling. And they love it, for they loathe Donald Trump both for who he is and what he stands for.
