Whatever happened to the investigation into Russian hacking of the 2016 presidential election?

It was supposed to be the biggest bombshell story of the 21st century, remember?

“Did Donald Trump or any of his associates on the campaign collude with Russia in hacking those emails and releasing them?” asked Sen. Tom Cotton of Arkansas yesterday. “That’s where we started six months ago.”

The FBI actually began their probe 11 months ago. And not one shred of evidence has ever been turned up, by the FBI, the CIA, the NSA, the House, the Senate or anybody else. But yesterday the Democrats were chasing their tails once again before Cotton finally got a chance to question Attorney General Jeff Sessions.

“We have now heard from six of the eight Democrats on this committee,” Cotton pointed out, “and to my knowledge, I don’t think a single one of them asked that question. They’ve gone down lots of other rabbit trails but not (asked) that question.”

Because they know the answer to the question. The answer is no Republicans colluded with Russians, period. Despite the torrents of fake news, neither Jeff Sessions nor anyone else in the Trump administration is a Russian double agent.

But the show must go on. So yesterday, the Democrats’ questions were all about… gossip, basically.

Mr. Sessions, just how p.o.’ed was the president of the United States that the former FBI director was too busy leaking anti-Trump memes to the New York Times to go out and tell the public that the president wasn’t in fact under investigation?

That was the question, asked in various ways over and over and over again. And when Sessions refused to answer, he was “impeding” the Democrats’ investigation — their investigation of how angry Trump was that his employee wouldn’t confirm that there was no investigation.

And when Sessions declined to take the bait, the Democrats were “troubled.” Because it was “problematic.”

Lois Lerner having the IRS persecute the Tea Party never troubled them. Nor did lying by the president about keeping your doctor and your health care plan, or Hillary’s whopper that Benghazi was caused by a Coptic Christian filmmaker.

None of that they found problematic.

The Democrats’ problem is that they still can’t accept the fact that they were beaten like a coal-mine pony by Donald Trump. How could they have lost to an orange fascist, as Reality Winner calls him. That’s the only real question Democrats have, but they can’t bring themselves to confront it. Surely it can’t be their own fault. So they go on TV and rant at the obese Russian ambassador — the “Kremlin spymaster,” they were calling him yesterday. At long last, have they no sense of shame? Of course not, they’re Democrats.

By the end of the hearing, the Democrats were reduced to accusing Sessions of being racist because he objected to being interrupted by Sen. Kamala Harris before he could answer her previous question. Nevertheless, he persisted. For her rudeness, Harris is hailed this morning as a rising political star and a great legal scholar, despite having flunked the bar exam the first time out. There’s a lot of that going around in Democrat political circles.

The Democrats claim to be shocked, shocked that the Russians tried to… do something last year. Of course, in 2016 Sessions was a U.S. senator from Alabama and Donald Trump supposedly had zero chance of being elected president. The Democrats controlled the executive branch, including all the intelligence agencies, yet were unable to prevent this cyber Pearl Harbor, which accomplished… what, exactly?

Well, who cares? I’m sure the overnight TV ratings will be boffo again, Kamala Harris is raising tons of money, and the Resistance can keep on resisting for another day.

Being a Democrat means never having to say you’re sorry.
