( Following is the conclusion of a two-part feature summing up the races for the Senate this November. The first part, including states not mentioned here. ran on Thursday. )

MAINE: The only question here is the margin of victory for Sen. Edmund Muskie. He is opposed, for the sake of form rather than out of hopes for victory, by an old style hack politician named Neil S. Bishop who has run unsuccessfully for a number of state-wide offices since he entered polities in the 1940S. Muskie won with 67 per cent of the vote in 1964 and will have to equal or top this to remain the front runner for the Democratic Presidential nomination in 1972.

MASSACHUSETTS: Hard times have fallen on the name Kennedy in the family's home state. With Chappaquiddick, Bobby Jr. getting busted for drugs, and Agnew getting 50 per cent approval in the state, Sen. Edward M. Kennedy will be hard pressed to equal his landslide victory of 1964.

The make or break figure being quoted for Kennedy is 60 per cent. If he can win with this margin or better he will still have a shot at the Presidential sweepstakes in 1972. President Nixon is hoping that the Republican candidate, Si Spaulding, will run well enough (40 per cent or better) to eliminate the Massachusetts Democrat from the national limelight. But Spaulding has a problem: he cannot figure out whether to go to the left to pick up disenchanted liberals or to the right for supporters of arch right winger Col. John McCarthy who lost the primary to Spaulding. Starting out as a strong Administration critic, Spaulding has retreated from his position since the Agnew attacks on Senator Goodell. The switch has not yet attracted the McCarthy voters, however, and may have wiped out any chance of Spaulding picking up the liberal support he must have to make a decent showing.

In contrast to the sorry Spaulding campaign, the Kennedy machine is well oiled and humming. His highly professional staff has de-emphasized the youth image and abandoned the massive students canvassing technique. The front door window of Kennedy's Boston office has about 50 pictures, only two showing the Senator with young people. Over 35 have Kennedy talking with hard hats, the elderly and middle Americans. The slickest is a picture of Kennedy meeting a VEW group under the sign "We support our boys in Vietnam."

How well the Kennedy magic will work remains to be seen. But with magic made up of money, seasoned staff, slick advertising, and a weak opponent, Teddy may be back in the ball game by '72.

MICHIGAN: Lenore Romney found that her name is as much mud as magic in the August 4 primary for the Republican Senatorial nomination. The wife of the Secretary of Housing and Urban Development squeaked by her opponent, State Sen. Robert Huber, with a scant 51 per cent of the vote. She must now face soft spoken liberal Senator Philip Hart in the general election. Hart has a good solid reputation as a defender of the consumer and as an opponent of trusts. He was an early opponent of the war and his wife was arrested in a 1969 peace demonstration, an incident which is a liability for the Senator.

Mrs. Romney has said that she would have voted against the Carswell nomination and that she supports wage and price guidelines (which Nixon opposes). She is also a loud critic of what she calls "pornography" and is against what she terms "militant women's groups." She is attractive and hard working, but not exactly a political genius. Hart should beat her soundly.

MINNESOTA: Twenty five years ago, Hubert H. Humphrey was elected Mayor of Minneapolis. He was a bright new liberal light, leader of the Democratic-Farm-Labor Party, and a anti-segregation spokesman at the 1948 Democratic convention. Since then Humphrey has been in Washington and Chicago, and neither sojourn did his career any good.

Humphrey is now trying to take back the Senate seat he held for over ten years. His opponent is Republican Rep. Clark McGregor, who has used Humphrey's long career to denounce him as a representative of the "old polities." McGregor, who supports "President Nixon's efforts to get an early and honorable peace in Vietnam," has denounced Humphrey for his 1969 statement that the war is a "great adventure." He has called the former Vice President "a sick man."

Humphrey has hit back by labeling McGregor's style "cheap, slick polities." McGregor will be hurt by his pro-Nixon record in the House and Humphrey by his own record as Vice President and 1968 Presidntial candidate. Humphrey is a clear favorite, and only a late McGregor surge could send him back to the drug store in Waverly.

MISSOURI: Stuart Symington, the three-term Senator from the "Show Me State," has changed in six years. In the 1964 campaign he was a leading advocate of a strong military and a vigorous effort to win in Vietnam. Since then, however, he has become a leading critic of the war and of big defense budgets (opposing the ABM, for example).

This switch has made it difficult for the Republican candidate, Missouri Attorney General John Danforth, to get his hooks into Symington. Danforth is a liberal and is regarded as the best Republican vote getter in the state. About the strongest criticism he has of Symington, however, is that he failed to oppose the war early enough. Danforth is running an expensive (he is heir to the Ralston Purina cereal fortune) and active campaign, but without issues it has been a uphill fight. It will be a major upset if he unseats Symington.

MISSISSIPPI: Incumbent Senator John Stennis, Chairman of the Armed Services Committee, was unopposed in the primary and is unopposed in the general election. That's Mississippi polities.

MONTANA: Incumbent Senator Mike Mansfield, Majority Leader of the Senate, faces only token opposition from Missoula, Montana, sporting goods salesman Bud Wallace.
