"By nominating petitions signed and filed as provided by existing laws party candidates for the office of United States Senator shall have their names placed on the official primary election ballots of their respective parties, in the manner herein provided for State offices, PROVIDED, HOWEVER, THAT THE VOTE FOR CANDIDATES FOR UNITED STATES SENATORS SHALL BE AN ADVISORY VOTE FOR THE PURPOSE OF ASCERTAINING THE SENTIMENT OF THE VOTERS IN THE RESPECTIVE SENATORIAL AND ASSEMBLY DISTRICTS IN THE RESPECTIVE PARTIES, and the Senatorial and Assembly nominees shall be at liberty to vote either for the choice of such district expressed at said primary election, or for the candidate for United States Senator who shall have received the endorsement of such primary election in the greater number of districts electing members of his party to the Legislature." [61] Stetson was not the only Senator to protest. Senators Campbell, Holohan and Miller sent to the Secretary's desk the following explanation of their votes: "We voted for the Direct Primary bill because it seems to be the best law that can be obtained under existing political conditions. We are opposed to many of the features of this bill, and believe that the people at the first opportunity will instruct their representatives in the Legislature to radically amend the same in many particulars, notably in regard to the election of United States Senators, and the provisions that prevent the endorsement of a candidate by a political party or organization other than the one that first nominated such candidate." A second protest, signed by Senators Curtin, Cartwright and Sanford, was also printed in the Journal. It reads as follows: "We voted to adopt the report of the Committee on Free Conference on Senate Bill No. 3, not because we believe it to be what is desired by the people of this State, but because we believe it to be the only bill that can be adopted at this late hour, as the Legislature is about to adjourn."
