Independent Candidates: To be placed on the general election ballot, a candidate for Attorney General without political party affiliation, like Graveline, must file an Affidavit of Identity and qualifying petition with at least 30,000 signatures of registered voters no later than “the one hundred-tenth day before the general election.”
Mich. Comp. Laws §§ 168.590c(2),
168.544f. This year, the filing deadline fell on July 19, 2018. To ensure they have enough valid signatures, unaffiliated candidates may submit as many as 60,000 signatures.
§ 168.544f. However, a candidate can only begin collecting signatures 180 days before the deadline, and, as part of the minimum number of signatures requirement, a qualifying petition must be signed by at least 100 registered voters in each of at least half of Michigan's 14 congressional districts.
See § 168.590b(3),
(4).
