The Secretary of State or any superintendent shall review the petition for compliance with the provisions of Code Section 21-2-170 and shall disregard any pages or signatures that are not in conformance with the provisions of that Code section. The Secretary of State or any superintendent may question the genuineness of any signature appearing on a petition or the qualification of any signer whose signature appears thereon and, if he or she shall thereupon find that any such signature is improper, such signature shall be disregarded in determining whether the petition contains a sufficient number of signatures as required by law. The invalidity of any sheet of a nomination petition shall not affect the validity of such petition if a sufficient petition remains after eliminating such invalid sheet.
