National & Minnesota Report

Because Minnesota became a state just prior to the Civil War (April 12, 1861 – April 9, 1865) and the adoption of its constitution on October 13, 1857, and includes Article I Bill of Rights Sec. 9. Treason defined. Treason against the state consists only in levying war against the state, or in adhering to its enemies, giving them aid and comfort. No person shall be convicted of treason unless on the testimony of two witnesses to the same overt act or on confession in open court.
Because Minnesota is a legislative state ballot access, though normally perfunctory, could deny Donald J Trump (R) ballot access through a legislative vote. The fact, the House of Representatives is the only legislative body on the ballot in 2024, means if both were to decide his name could be denied and any written ballot, would be considered spoiled.
Subd. 6.Candidate’s eligibility to hold office.

(1) has been convicted of treason or a felony and the person’s civil rights have not been restored;

(2) is under guardianship in which the court order revokes the ward’s right to vote; or

(3) has been found by a court of law to be legally incompetent;
