Goldberg: The Mueller report is in, but the collusion story may never end

But it does not — and really cannot — put to rest the softer versions of the collusion charge. Candidate Trump publicly called on the Russians to keep hacking away at Hillary Clinton's emails. Don Jr. and the entire senior leadership of the Trump campaign took a meeting with a self-declared emissary of the Russian government to get dirt on Hillary (and then lied about it later at the president's direction). Mr. Trump's campaign manager, currently in prison, worked with Russian-aligned oligarchs in Ukraine. Various campaign peons and hangers-on were eager to cultivate relations with Russia.

Moreover, the ironclad conclusion of the intelligence community as well as the Mueller investigation found that Russia did indeed work to get Mr. Trump elected. The Trump campaign may have been dishonorably happy for the help, but that's not collusion.

And let's be clear: That is very good news. If you believed that Mr. Trump was a traitor, it's one thing to want that exposed, quite another to want it to be true, which is where a lot of people ended up.

Those people will not go away, nor will they lose their adamantine convictions about the president's fitness or legitimacy.

Which is one of the reasons why this will remain a never-ending story.

Like Hillary Clinton, Mr. Trump is an avatar in a broader culture war. We're still hearing about Ms. Clinton's emails. Why should we expect the clamor over Mr. Trump's alleged collusion to end any time soon?

Beto O'Rourke, who, like most of his competitors for the Democratic nomination, is trying to personify the collective liberal id, simply ignored the news and proclaimed that he believed "beyond the shadow of a doubt" that Mr. Trump sought to collude with Russia.

Similarly, just as there are people irretrievably locked into the idea that Mr. Trump is illegitimate, there are legions of people equally committed to the idea that the probe itself was an illegitimate witch hunt, or, in the president's words, an attempted "illegal takedown."

Never mind that the same people who insisted that Mr. Mueller was a dirty deep-state operative doing the Clintons' bidding are now celebrating Mr. Mueller's integrity and thoroughness. (Last July, Rudy Giuliani called the probe "the most corrupt investigation I have ever seen.")

Both the collusion and deep-state narratives have always been subordinate to the larger and deeper motives driving and sustaining political polarization.

New facts — Mr. Trump didn't collude, Mr. Mueller wasn't corrupt — are like rocks in a river. They will divert the water here or there, and perhaps create some froth and churn, but the torrent won't stop, particularly when there are so many fresh avenues for the waters to follow.

The watchword on the right these days is "reckoning" — as in, there needs to be one for anyone who believed Mr. Trump colluded or even supported an investigation. On the left, there is a clamor for Congress to pick up where Mr. Mueller left off and a hunger for new saviors, such as the U.S. Attorney for the Southern District of New York.

The idea that the Mueller report itself will remain secret is a childish fantasy. And although Mr. Barr's summary may be technically accurate, one can be sure it is not comprehensive.

It is too tempting a treasure trove of anti-Trump spoils for Democrats and journalists to ignore. Likewise, all of the documents — warrants, internal memos, etc. — that birthed the investigation in the first place are too delicious for those seeking a reckoning to remain warehoused like the Ark of the Covenant in the first Indiana Jones movie.

A chapter has closed, but the story goes on. Because too many people need it to.
