President Donald Trump is openly hinting at taking over the midterm elections by declaring a national emergency.

Newsmax’s Wayne Allen Root interviewed Trump just after midnight Tuesday morning, and said that Trump had the right to declare a national security emergency next month, forcing through photo identification, proof of citizenship, limits on mail-in ballots, and other heavy voting restrictions. Trump seemed to like that suggestion, but didn’t want to tip his hand.

“Let me just say stranger things have happened, okay? I’ll leave it at that,” Trump said.

Trump is afraid of massive Republican losses in November’s midterms, and has been unsuccessfully pushing his allies in Congress to pass the draconian SAVE Act. With that appearing more unlikely each day, Democrats and other Trump critics are raising concerns that he may take drastic action, such as declaring a national emergency and maybe deploying legions of Immigration and Customs Enforcement agents to the polls.

In fact, Democrats have been trying for close to a year to get documents from the Department of Homeland Security regarding its policies and memos on sending ICE agents to polls. Agents were seen at polling places in Texas during its May primaries and in California in June, but when Democrats used the Freedom of Information Act to investigate, they were sent useless press clippings.

If Trump tries to invoke national security to take over federal elections, it would shatter precedent and could set off lawsuits and protests across the country. His repeated, disproven claims about voter fraud and rigged elections suggest that he’ll make the same excuses in November. The question is how to ensure a fair and accurate result that can stand up to his attacks.
