Not only do Democrats fashion themselves the protectors of “democracy,” they claim to be champions of decency.

Well, if the second day of the Democratic National Convention is any indication, the left doesn’t have any claim on the high moral ground.

For one thing, no one at the DNC seemed even mildly constrained by the truth.

More than once, for instance, Democrats falsely claimed that Trump had referred to the Tiki Torch Nazis of Charlottesville as “very fine people.”

Democrats also falsely accused the former president of instructing Americans to “inject bleach” during the COVID pandemic.

Chuck Schumer, who’s painstakingly ignored the ugly and often violent Jew-hatred that’s infected his party, accused Trump of peddling anti-Semitism.

Speaker after speaker warned that Donald Trump, a relative moderate on social issues, was going to ban in vitro fertilization, even though the former president has explicitly rejected any limits on fertility treatments.

So it made all the sense in the world that the second night of the DNC featured former president Barack Obama, a man who probably did more to polarize American politics than any in modern history.

And the vacuous religiosity and hypocritical moralizing of Obamas was on full display.

It began with the former president’s wife Michelle, a strong speaker who can deliver a mind-bending platitude with the best of them.

Follow along with The Post’s live reporting of the Democratic National Convention in Chicago.

Michelle preemptively accused anyone who opposed the Dems presidential nominee Kamala Harris of being driven by racism and misogyny — basically, the same con the Obamas ran when they were in the White House.

When it was former president Obama’s turn, he lamented the ugliness of modern American politics before mocking Trump’s “weird obsession with crowd sizes” by gesturing with hands to signify a small length.

Obama bemoaned that our politics had turned citizens against each other, before accusing Republicans of being insular slacked-jawed hate mongers.

As George Will once wrote, Obama is “a pyromaniac in a field of straw men.”

But perhaps the most confusing aspect of the night was Obama’s call for a return to decency. The former president, in fact, argued that America needed, “a new chapter, a better story,” even though his own vice president Joe Biden has been in office for nearly four years.

Come to think of it, Kamala Harris had also been in office for nearly four years. What had either done to make our politics less divisive or our lives more joyful?

Politics is indecent in America today as it has been for a long time. And the DNC offered us another example of how low we’ve sunk.
