A Lawfare analysis by Loren Voss and Natalie K. Orpett argues that the Insurrection Act does not create an exception to the federal statute prohibiting troops at polling places. The authors point to 18 U.S.C. § 592, which has barred military officers and civilian federal leaders from deploying troops or armed men to election sites for more than 160 years. The only exception, added in 1909, is when force is necessary to repel armed enemies of the United States.
The Insurrection Act, codified at 10 U.S.C. §§ 251–253, grants the president authority to use the military to suppress insurrection, domestic violence, unlawful combination, or conspiracy. But the authors note that none of the Insurrection Act's conditions maps onto the § 592 exception. Satisfying the Insurrection Act's requirements, they write, does not establish that troops are needed to repel armed enemies. The statutes are not inconsistent, and the historical context supports reading § 592 as a restraint on the president's deployment authority.
The piece emphasizes that the original 1865 version of § 592 included a second exception for keeping the peace at the polls, which Congress later deliberately removed. That removal, along with the statute's mandatory disqualification from federal office for violators, underscores the strength of the ban. The authors conclude that even under the Insurrection Act, armed personnel cannot lawfully be sent to polling locations.
