Each signer of a nomination petition shall sign but one such petition for each office to be filled, and shall declare therein that he is a registered and enrolled member of the party designated in such petition: Provided, however, that where there are to be elected two or more persons to the same office, each signer may sign petitions for as many candidates for such office as, and no more than, he could vote for at the succeeding election. He shall also declare therein that he is a qualified elector of the county therein named, and in case the nomination is not to be made or candidates are not to be elected by the electors of the State at large, of the political district therein named, in which the nomination is to be made or the election is to be held. He shall add his address where he is duly registered and enrolled, giving city, borough or township, with street and number, if any, and shall legibly print his name and add the date of signing, expressed in words or numbers: Provided, however, that if the said political district named in the petition lies wholly within any city, borough or township, or is coextensive with same, it shall not be necessary for any signer of a nomination petition to state therein the city, borough or township of his residence. No nomination petition shall be circulated prior to the thirteenth Tuesday before the primary, and no signature shall be counted unless it bears a date affixed not earlier than the thirteenth tuesday nor later than the tenth tuesday prior to the primary.
