Former Democratic presidential candidate Hillary Clinton issued a dire warning about a right-wing effort to "steal the next presidential election."

In a promotional video for progressive advocacy organization Indivisible Guide, Clinton said that the future of American democracy lies in Moore v. Harper, a pending United States Supreme Court case related to the independent state legislature theory (ISL), arising from the redistricting of North Carolina's districts following the 2020 Census.

The case would determine the extent to which state legislatures can independently set election rules, suggesting that Republican-controlled legislatures might ignore election results and submit a fraudulent set of electors beholden to the GOP majority.

Clinton cautioned that the Supreme Court "may be poised to rule on giving state legislatures the power to overturn presidential elections," signaling to prospective voters what is at stake should Republicans regain power following next month's midterm elections.

Clinton said:

"Hello Indivisibles, I'm here to highlight something that is keeping me up at night, and I know this group really understands what I am about to say."

"I know we're all focused on the 2022 midterm elections and they are incredibly important. But we also have to look ahead, because you know what? Our opponents certainly are."

“Right wing extremists already have a plan to literally steal the next presidential election. And they’re not making a secret of it."

"The right wing-controlled Supreme Court may be poised to rule on giving state legislatures the power to overturn presidential elections."

"Just think, if that happens, the 2024 presidential election could be decided not by the popular vote or even by the anachronistic Electoral College but by state legislatures, many of them Republican-controlled."

But, Clinton continued, there is "very good news in the face of this very real threat to democracy."

She announced that Indivisible Guide had launched Crush the Coup, an effort to flip key seats to stop Republicans from regaining control and potentially overturning voters’ choice in presidential elections in 2024 and beyond.

Clinton noted that the organization has put together a list of "critical races in six key states"—Arizona, Georgia, Michigan, North Carolina, Pennsylvania, and Wisconsin—that Indivisible notes "are trending blue in presidential elections but ruled by Republican state legislatures."

Clinton's warning resonated with many who have amplified her call to action.

Since conceding the election to former Republican President Donald Trump, Clinton has remained a visible force within the Democratic Party even as Trump often cast doubt on the legitimacy of the election he supposedly won and regularly attacked her while in office.

Clinton has also often faced calls to "lock her up" since the 2016 general election.

In July 2016, Trump, then a presidential candidate, invited Russia to hack Hillary Clinton's emails, asking the Kremlin to find "the 30,000 emails that are missing" from the personal server she used during her tenure as Secretary of State.

As Secretary of State, Clinton responded to the Arab Spring by advocating military intervention in Libya but was harshly criticized by Republicans for the failure to prevent the 2012 Benghazi attack. However embassy security staff was cut by Republicans prior to the attack.

Her use of a private email server when she was Secretary of State was the subject of intense scrutiny. The emails were retrieved, not deleted as Republican rhetoric claims. No charges were filed against Clinton as it was deemed a procedural issue and not criminal.

Multiple members of the Trump administration were cited for using private servers, unsecured electronic devices and public apps for official White House communication.
