WHO'S NEW IN THE SENATE

Alaska. Massachusetts-reared Maurice Robert ("Mike") Gravel, 38, has been in Alaska only since 1956, but he upset veteran Senator Ernest H. Gruening in a tough primary battle. Gruening's angry ensuing write-in campaign and a vigorous challenge from Republican Opponent Elmer E. Rasmuson made the general election a cliffhanger, but now Gravel, onetime speaker of the Alaska house, will have a chance to speak for his state in the Senate.

Arizona. "Senator Barry Goldwater," his campaign ads burbled. "Doesn't that sound great?" Arizona voters agreed, despite an energetic campaign waged by Democratic Opponent Roy Elson, 38, longtime aide to retiring Senator Carl Hayden, and Hayden's choice for the seat. Goldwater complained that his 1964 followers "have no voice in the Government today" and promised to remedy the situation.

California. Alan Cranston shaped his liberal leanings at the front, reporting on the activities of Mussolini's legions in Ethiopia. After World War II service as OWI foreign-lan-guage chief, Cranston became a staunch world federalist, then helped found the liberal California Democratic Council. In 1958 he became California's first Democratic Controller in 72 years. A former Stanford track star, Cranston, 54, easily ran past his Republican opponent, the state's fustian Superintendent of Public Instruction, Max Rafferty.

Florida. A native of Maine, Edward J. Gurney migrated to Florida in 1948, was later elected mayor of Winter Park, and, in 1962, a U.S. Representative. Now he becomes the first Republican since Reconstruction to be sent to the Senate from Florida. To defeat former Democratic Governor LeRoy Collins, Conservative Gurney ran on a record that includes votes against civil rights legislation, foreign aid, and that "expensive boondoggle," the war on poverty.

Iowa. In three terms as Iowa's Governor, Harold E. Hughes, 46, has established himself as an independent and popular liberal. A handsome former truck driver who entered politics when he became angry at the state Commerce Commission, Democrat Hughes was enlisted for the Senate race by Robert Kennedy. A Viet Nam dove and gun-control advocate in a hawkish, rifle-owning state, Hughes was hard pressed by Republican David Stanley, but lowans decided to send their Governor to Washington.

Kansas. Republican Congressman Bob Dole, long a staunch conservative, has become more of a moderate this year in his race for Veteran Senator Frank Carlson's Republican seat. Author of a Food-for-Peace amendment that now sends U.S. farmers as technical advisers abroad, Nixon-back-er Dole easily beat out Democratic Candidate William I. Robinson, a Wichita lawyer. Kentucky. As chief executive officer of Jefferson County (Louisville), Republican Marlow W. Cook, 42, was prepared for advancement. His hard-line policy on Viet Nam and tough stand on riots appealed to Kentucky voters more than the moderately liberal philosophy of his Democratic opponent, former Kentucky Commissioner of Commerce Katherine G. Peden, only woman member of the Kerner Commission on Civil Disorders.

Maryland. Liberal Republican Charles McCurdy Mathias Jr. can thank an indefatigable Irishman for sending him to the Senate. The vote for Independent George P. Mahoney, an eight-time loser of Wallace-type opinions, cut into the total for liberal Democratic Incumbent Daniel B. Brewster. Winner Mathias, 46, a hard-working House member since 1961, has backed civil rights, education bills, Medicare, Appalachian aid, rent supplements and even rat control.

Missouri. Lieutenant Governor Thomas F. Eagleton, 39, was elected to his current office in 1964 with 65% of the vote. Last summer he toppled Democratic Incumbent Edward V. Long in the primary. Now he has defeated an 18-year veteran of the House, scholarly, industrious Republican Thomas B. Curtis. The Kennedyesque liberal (Teddy made a campaign film with him) promises to be tall on domestic spending but short on military appropriations.

Ohio. Law and order is a big issue in Ohio this year, and it helped send Ohio Attorney General William Saxbe, 52, to the Senate. A moderate Republican, Saxbe used the issue handily against Democratic Opponent John J. Gilligan, who had criticized draconian court handling of Cincinnati rioters. Saxbe also promoted jobs, better education, clean air and water, and "our last Viet Nam."

Oklahoma. "Basically I am a conservative," explains Republican Henry Bellmon, "but I am sure as hell not a John Bircher or an isolationist." His political acumen made Bellmon, now 47, the first Republican Governor (1963-67) in Oklahoma's 61-year history, and now sends him to the Senate. Mindful that he overturned able Democratic Veteran Senator Mike Monroney with the argument that Monroney, 66, had lost touch with his grass roots, Rancher Bellmon is not likely to spend all his time in Washington.

Pennsylvania. To get into Congress in 1960, Republican Richard S. Schweiker had to buck G.O.P. pros. Now he has ousted two-term Democratic Senator Joseph S. Clark. A prosperous tile manufacturer and a Schwenkfelder--a member of one of Pennsylvania's "plain" sects--Schweiker, 42, does not smoke, rarely drinks, and then only wine. A self-styled moderate, he is an outspoken civil rights champion and an earnest advocate of draft reform.
