What if all the interventions in the 2016 presidential election by "Russians" actually were Democrats posing as Russians?

Talk-radio host Rush Limbaugh tossed that bombshell into the political discussion Monday, saying it wouldn't surprise him because he has evidence the Democrats did exactly that in the 2017 special Senate election in Alabama.

He cites a tech billionaire's confession to paying the bill.

WND reported the Democrats researched how Russians used social media to influence the 2016 election and deployed the same tactics against Judge Roy Moore in the special election in Alabama.

Later, LinkedIn's Reid Hoffman admitted partly funding a group of Democrats that used "disinformation tactics" in the race, which was won by Democrat Doug Jones.

Facebook later suspended five accounts tied to the disinformation campaign, and elections officials in Alabama said they were investigating.

"They created misleading Facebook pages, urged Republicans in Alabama to support a write-in candidate instead of Roy Moore, and 'created false evidence that bots were backing Moore on Twitter' to spur misleading news headlines," a report about the dark web tactics said.

It was known as Project Birmingham.

Hoffman said he was disturbed by what happened, and he apologized.

"I want to be unequivocal: there is absolutely no place in our democracy for manipulating facts or using falsehoods to gain political advantage," Hoffman told the Washington Post.

The Democrats posed as conservatives on Facebook "to try to divide Republicans and even to endorse a write-in candidate to draw votes from Mr. Moore," the New York Times said.

"It involved a scheme to link the Moore campaign to thousands of Russian accounts that suddenly began following the Republican candidate on Twitter, a development that drew national attention."

An internal report on the strategy against Moore was obtained by the Times. It said, "We orchestrated an elaborate 'false flag' operation that planted the idea that the Moore campaign was amplified on social media by a Russian botnet."

It used Facebook and Twitter for its channels of information.

Limbaugh noted Hoffman's confession about the "misinformation campaign, which falsely linked Republican Senate candidate Roy Moore to Russian-influence operations.

"It was a test-market kind of thing," Limbaugh said. "They were testing this for future operations, and the media totally fell for it. … In other words, this operation was made to look like the Russians wanted Roy Moore to win — 'and media fell for it'! The media reported that it looks like Russians are interfering in the Alabama Senate race, and it was 'used to gin up opposition to Roy Moore as they were following on the coattails of the entire deep-state disinformation campaign that the Russians had been helping Trump.'

"In other words, this guy did everything the Democrats are railing against! This guy, Reid Hoffman, did everything the Democrats are using the Mueller investigation to ferret out! This guy did it, and camouflaged it to make it look like a Russian operation!" Limbaugh said.

Limbaugh then posed a warning to America: "Now, if this happened, could it not also be the case that Hillary Clinton and the DNC and a bunch of people in that whole operation from Fusion GPS to Christopher Steele also engaged in a similar false flag operation to make it look like Russians were involved when no Russians were, or very few?

"We know there’s some Russian troll farms that were engaging in bot operations after the election. But what if the truth of the matter is that there weren't any Russians, it was a bunch of activist Democrats making it look like Russians. We've alleged to this, we've acknowledged the possibility of this. And what, therefore, if the entire Mueller investigation is nothing more than an effort to make sure nobody ever learns this?"
