There is no recall provision in Maine. This is symbolic.
i don’t know how old this is- maybe it’s changed?
RECALL
§ 1301. Recall; grounds for recall
Every elected official in the State is subject to recall by the voters of the district in which the official is elected as provided in this chapter. Grounds for recall are neglect of duty, misuse of office or incompetence in the performance of duties when that neglect of duty, misuse of office or incompetence in the performance of duties has a material and adverse effect upon the conduct of the office; conviction of a drug-related crime; criminal conduct; corruption; misappropriation of public funds; obstruction of voter-approved initiatives; or violations of ethics laws. A petition for recall may not be filed against an elected official until the elected official has actually performed the duties of the office to which elected for a period of 6 months during the current term of that office. A petition may not be filed against an elected official during the last 6 months of the official’s term of office. An elected official who is the subject of a petition shall continue to perform duties of the office until the result of the recall election is certified.
§ 1302. Recall petition; number of signatures
A petition to recall an elected official must be signed by a number of voters of the district in which the official is elected equal to not less than 15% of the number of votes cast for candidates for that office at the last preceding election in the electoral district of the elected official. The party affiliation of signatories to a petition must be proportional to the party affiliation of the voters who cast votes for candidates for that office at the last preceding election in the electoral district of the elected official.
