Democrats are working quietly to bring into the mainstream the narrative that GOP victories are by default illegitimate, thereby weakening and undermining duly elected Republican officials.

It is dangerous stuff — just as dangerous as when President Trump questioned the legitimacy of the 2016 election, which Democrats and the media rightly condemned as a threat to a healthy, functioning republic. But that was when Democrats thought their hold on the White House was a sure thing. It is funny how the shoe ends up on the other foot.

The latest example of Democrats casting doubt on the legitimacy of Republican victories in advance came Friday as 2020 hopeful Sen. Elizabeth Warren, D-Mass., spoke at Al Sharpton’s National Action Network Convention.

"Massive voter suppression prevented Stacey Abrams from becoming the rightful governor of Georgia,” she said, reciting a falsehood that has now become an article of faith in the Democratic Party.

Warren added, "They know that a durable majority of Americans believe in the promise of America, and they know that if all the votes are counted, we'll win every time."

Warren is not just ensuring that there will be an excuse should she lose an election, as Hot Air’s Allahpundit rightly notes. The senator’s statement was made in reference to all elections, which is far more sinister than Trump’s own ego-driven flirtation in 2016 with the idea that the race would be "rigged" by "illegal" votes against himself. Also, it should not be ignored that Warren's message was delivered to an almost exclusively African American audience. The senator was very clearly saying: Republicans only win when they cheat, and they only win when they suppress your vote.

Again, this is some dangerous stuff, encouraging specific voting blocs to believe that U.S. elections are rigged. It should not be surprising that Democrats are going down this road, though. This much became apparent in January when Senate Minority Leader Chuck Schumer, D-N.Y., announced that Abrams, an election truther, would deliver the Democratic Party’s response to Trump’s State of the Union address.

“She has led the charge for voting rights, which is at the root of just about everything else,” the senator said.

Abrams’ chief claim to fame right now in the Democratic Party is that she refuses to concede she lost last year's Georgia gubernatorial race. Though she terminated her campaign eventually, she maintains, without evidence, that the race was stolen by Georgia’s then-Secretary of State Brian Kemp, who won 50.2 percent of the vote (compared to her 48.8 percent).

Schumer’s emphasis on Abrams’ “voter rights advocacy,” coupled with Democrats’ repeated claims that the 2016 election was rigged in Trump’s favor, suggested clearly at the time that they fully plan to go all-in on the idea that Republicans rely on “voter suppression tactics” to win elections. On Friday, as Warren assured a roomful of African Americans that the GOP wins only when it suppresses the black vote, we saw both a continuation and a confirmation of the Democrats' dangerous campaign to delegitimize free and fair U.S. elections.
