Efforts follow to remove Trump from the 2024 ballot

Formal challenges to Donald J. Trump’s presidential candidacy have been filed in at least 33 states, according to a New York Times review of court records and other documents. Mr. Trump was disqualified from the primary vote in Colorado and Maine pending appeals, but many other lawsuits have been dismissed or not heard in court. Outside of Colorado and Maine, at least seventeen states still have unresolved problems.

The voting challenges focus on whether Trump’s efforts to overturn his 2020 election defeat make him ineligible to run for president again. These cases are based on an obscure and largely untested clause of a constitutional amendment enacted after the Civil War that disqualifies government officials “engaged in insurrection or rebellion” from holding office.

The Colorado Supreme Court and Maine’s secretary of state, a Democrat, both found that Mr. Trump was ineligible under that provision. Mr Trump, who is leading in the Republican primaries, can appeal these decisions. His campaign describes efforts to remove him from the ballot as unconstitutional and antidemocratic.

Several judges have dismissed cases at the request of Mr. Trump or at the request of the person who filed the challenge. The Supreme Courts of Michigan and Minnesota have both said that Mr. Trump is eligible to appear on the primary ballot in those states.
