who would qualify as a electors
Answers
The U.S. Constitution contains very few provisions relating to the qualifications of Electors. Article II, section 1, clause 2 provides that no Senator or Representative, or Person holding an Office of Trust or Profit under the United States, shall be appointed an Elector. As a historical matter, the 14th Amendment provides that state officials who have engaged in insurrection or rebellion against the United States or given aid and comfort to its enemies are disqualified from serving as Electors. This prohibition relates to the post-Civil War era.
The National Association of Secretaries of State (NASS) has compiled a brief summary of state laws about the various procedures, which vary from state to state, for selecting slates of potential electors and for conducting the meeting of the electors. The document, Summary: State Laws Regarding Presidential Electors, can be downloaded from the NASS website.
Each state's Certificates of Ascertainment confirms the names of its appointed electors. A state's certification of its electors is generally sufficient to establish the qualifications of electors.
