Here’s the most interesting part: Now that they’ve been called on it, the media and Democrats are gradually retreating from the investigation they’ve been touting for months as the glue for their conspiracy theory. It’s actually quite amusing to watch: How dare you suggest President Obama would ever order surveillance! Who said anything about FISA orders? What evidence do you lunatic conservatives have — uh, other than what we media professionals been reporting — that there was any investigation of the Trump campaign?

You will hear more righteous indignation in the coming days, no doubt. The first brushback pitches came this weekend: the claim that if President Trump dares to demand that the FBI and Justice Department show him the supposed FISA applications, he will be engaged in unprecedented political interference in the independence of law enforcement. It’s a silly assertion; as I explained over the weekend, FISA surveillance is not law enforcement, it is national security. A chief executive who demanded to review FISA information (obtained by exercise of the executive’s power) would be doing his main job — to protect the country — not interfering in a judicial proceeding.

But have you noticed? While all this head-spinning legal jibber-jabber goes back and forth, the foundation of the false narrative we’ve been hearing since November 8 has vanished. Now that we’re supposed to believe there was no real investigation of Trump and his campaign, what else can we conclude but that there was no real evidence of collusion between the campaign and Russia . . . which makes sense, since Russia did not actually hack the election, so the purported objective of the collusion never existed.
