They now play the race card in every hand—because often it works.

p> Democrats are taking racial politics to new heights—and no wonder, since the tactic has again succeeded. This week Republican Senator Tim Scott said he will oppose the nomination of Thomas Farr, tapped for a federal judgeship in North Carolina. Senator Jeff Flake is voting no to showcase his opposition to Donald Trump, and the two GOP defections are enough to torpedo Mr. Farr’s appointment this year.

There’s no reason to doubt the sincerity of Mr. Scott, the Senate’s only black Republican. But Democrats will see Mr. Farr’s defeat as a vindication of their most underhanded and inflammatory racial tactics.

Consider a second complaint against Mr. Farr: that the North Carolina Legislature retained him to defend its 2013 voter-ID law. “This is a man who stands for disenfranchisement of voters, particularly minority voters,” Senate Minority Leader Chuck Schumer said this week.

This is racial demagoguery.

a bipartisan commission on election reform, led by former President Jimmy Carter and former Secretary of State James Baker, endorsed the idea of a photo-ID requirement. “Voters in nearly 100 democracies use a photo identification card without fear of infringement on their rights,” the report said. The commission also said that ballot integrity is “a hallmark of democracy.” Was Jimmy Carter harboring racist motivations?

Another case of trying to rile up racial division was this week’s Senate runoff in Mississippi. Republican Cindy Hyde-Smith was assailed for using a clumsy joke to flatter one of her supporters. “I would fight a circle saw for him,” she said. “If he invited me to a public hanging, I’d be on the front row.” The national media portrayed this as a coded reference to Jim Crow-era lynchings, which is ludicrous.

In Florida, some supporters of the Democratic gubernatorial candidate, Andrew Gillum, are saying he lost because he is black. But even among black voters, the progressive Mr. Gillum underperformed by four percentage points Democratic Senator Bill Nelson, who also lost. In Georgia, Democrat Stacey Abrams blamed her gubernatorial defeat on “systemic disenfranchisement, disinvestment and incompetence,” despite massive turnout for a midterm election. *** For two years, Democrats have denounced President Trump’s rhetoric as divisive, and sometimes they’ve been right. Yet they’re also only too happy to polarize the electorate along racial lines, insinuating that Republicans steal elections and pick judges who nurse old bigotries. That tactic now appears to have sunk Mr. Farr’s nomination, which is a shame. The only way to discourage these unmoored racial attacks is to ensure they don’t work.
