In a rare moment of clarity on Thursday, MSNBC’s Chris Matthews stumbled onto a chestnut of truth: former FBI director James Comey’s testimony had destroyed the key Democratic narrative coming out of 2016. Matthews explained:

The assumption of the critics of the president, of his pursuers, you might say, is that somewhere along the line in the last year is the president had something to do with colluding with the Russians … to affect the election in some way. And yet what came apart this morning was that theory.

Matthews continued by stating that “Flynn wasn’t central to the Russian investigation,” asking, “where’s the there-there?”

The problem is this: while Matthews is eminently correct, two things are now happening. First, the left is pivoting — they’re already jumping on supposed “obstruction” by Trump in the Flynn investigation, even though Comey said that Trump never tried to shut down the Russian investigation. According to Comey, Trump “directed” him to drop the investigation into Flynn’s unreported phone calls to the Russians, but Comey also admitted that wasn’t implicit in Trump’s actual language. And as Matthews says, there’s still no evidence of any actual crime in Flynn discussing matters with the Russians before becoming National Security Advisor.

Second, Trump is blowing his opportunity to jump on the Matthews narrative. This is the only narrative that matters: that the Left constructed out of whole cloth a fantasy whereby Hillary Clinton only lost because Trump was working hand-in-glove with Vladimir Putin, and now they’re out on a limb — and Comey just cut the limb off. Instead, Trump feels the need to go toe-to-toe with Comey on the details of their conversations, even though Comey has now testified under oath. That’s foolish.

But there is no doubt that Comey’s testimony debunked the leading narrative purveyed by the Left since the election. And even Chris Matthews knows it.
