If the time between the date on which the last signature is affixed and the date on which the petition is submitted for filing exceeds 60 days, or, if any signature on the petition has been secured more than six months from the date on which the first signature was affixed, the petition shall be considered insufficient and shall be filed by the clerk as a public record without prejudice to the filing of a new petition.
