FOLLOWING IS a partial list of House incumbents who have been squeezed or weakened by redistricting decisions. The estimates are based almost solely on the way the lines were drawn, and not on judgments on the strength of the 1982 candidates.

ALABAMA -- Freshman Rep. Albert Lee Smith (R), who won with 51 percent last time, picks up additional territory around Birmingham, which both parties say makes him marginally more vulnerable.

CALIFORNIA -- Rep. Robert K. Dornan (R), whose district was dismembered, went into the June Senate primary, where he lost along with Reps. Barry M. Goldwater Jr. (R) and Paul N. (Pete) McCloskey Jr. (R), whose districts are expected to be held by other Republicans. Reps. David Dreier (R) and Wayne R. Grishman (R) were forced into the same district, with Dreier the survivor. Rep. John Rousselot (R) was moved into a heavily Hispanic district, where he faces a hard fight against Assemblyman Matthew G. (Marty) Martinez (D).

Rep. Don Clausen (R) faces Assemblyman Douglas Bosco (D) in a district where Clausen is weakened by the new lines. Ironically, the Democrat most hurt by redistricting is the plan's author, Rep. Philip Burton (D), who gave away some of his Democratic precincts in San Francisco to balance the Bay Area districting. Burton faces state Sen. Milton Marks (R), a good vote-getter. Rep. Tom Lantos (D) traded blue-collar Daly City for independent Palo Alto (Stanford University) and could have more problems in his rematch with ex-Rep. Bill Royer (R).

COLORADO -- Rep. Ray Kogovsek (D) keeps his Pueblo base but picks up large new territory on the western slope of the Rockies and faces a major GOP challenge.

FLORIDA -- Rep. Bill Chappel Jr. (D) had his home county severed from his district, but is expected to be reelected. Rep. Bill McCollum (R) did not get the lines he wanted and faces a potentially strong challenge from state Rep. Dick Batchelor (D).

GEORGIA -- Either Rep. Elliott H. Levitas (D) or Rep. Wyche Fowler Jr. (D) or both may be vulnerable, depending on how the courts finally set the district lines in the Atlanta area. If blacks are concentrated in Fowler's district, he could face a serious primary challenge, and the loss of blacks could make Levitas more vulnerable to a Republican in November.

ILLINOIS -- Two Republicans have already been squeezed out, and more may be vulnerable in November. The court-ordered lines put Reps. Robert McClory and Edward Derwinski in with fellow Republicans. McClory bowed out and Derwinski lost in the March primary to Rep. George O'Brien. The new lines make life more difficult for House Minority Leader Robert Michel and Reps. Daniel Crane and Paul Findley, with Findley facing a particularly tough challenger in Richard J. Durbin (D).

INDIANA -- The Republican plan put Reps. Andrew Jacobs (D) and David W. Evans (D) into the same district, and Jacobs won the May primary. Rep. Floyd Fithian (D), whose district was carved, is running for the Senate against incumbent Richard Lugar (R). Rep. Philip R. Sharp (D) faces Ralph Van Natta (R) in a district redrawn to favor the GOP. Rep. Lee Hamilton (D) was forced to move when his home was separated from his district, but he has a safe seat.

IOWA -- Rep. Cooper Evans (R) faces his 1980 opponent, Democratic Party vice chairwoman Lynn Cutler, in a district redrawn to include Johnson County, home of the University of Iowa, where Reagan received less than one-third of the 1980 vote. He is rated one of the most vulnerable of the freshman Republicans.

KANSAS -- A week after the federal court handed down its plan, adding Douglas County, home of the University of Kansas, to a district already including Kansas State University, conservative Rep. Jim Jeffries (R) announced his retirement. The GOP hopes a more moderate candidate can hold the seat, but it may be tough.

KENTUCKY -- Population loss in Louisville forced Rep. Romano L. Mazzoli (D) to pick up more suburban territory, but he was allowed to choose his own suburbs and is favored over Jefferson County commissioner Carl Brown (R). Conversely, Rep. Larry J. Hopkins (R) lost some helpful suburbia, but the final plan preserved his Lexington base, helping him against former newspaperman and state official Don Mills (D).

MARYLAND -- Rep. Clarence D. Long (D) lost two heavily Jewish neighborhoods that had supported him, but he retains enough of his political base in Baltimore County to be at least a slight favorite.

MASSACHUSETTS -- Reps. Margaret M. Heckler (R) and Barney Frank (D) were forced into a November shootout, with territory favoring Hecker in what figures to be a very close race.

MICHIGAN -- Freshman Rep. Jim Dunn (R) was weakened by redistricting, which added Pontiac and its unemployment to his territory, and faces an exceptionally tough rematch with ex-Rep. Bob Carr (D).

MINNESOTA -- Redistricting created a collision between two Republicans, conservative Rep. Tom Hagedorn and moderate Rep. Arlen Erdahl, resolved recently when Erdahl agreed to move into largely unfamiliar territory in suburban Minneapolis-St. Paul, where he faces a tough race. Also weakened slightly was Rep. Arlan Stangeland (R), who will probably face the same Democrat, Gene Wenstrom, he defeated narrowly twice before.

MISSISSIPPI -- Rep. David R. Bowen (D) ended his bid for reelection last week after the Supreme Court approved a court-drawn plan making Bowen's a black-majority district.

MISSOURI -- Two Republicans were moved into new territory and tougher races. Rep. Bill Emerson lost his home county and was moved from the St. Louis suburbs into southeastern Missouri counties formerly served by Rep. Wendell Bailey. Bailey moved west to challenge Rep. Ike Skelton (D) in the redrawn 4th District running from Jefferson City to the Kansas City suburbs. Addition of suburban territory has reduced the black percentage for Rep. William L. Clay (D), and he faces a serious primary with a white opponent.

NEW JERSEY -- Republicans lost one seat in the carving of the district now held by their Senate nominee, Rep. Millicent Fenwick. Two other incumbent Republicans, Reps. Christopher H. Smith and Harold C. Hollenbeck, were weakened. Smith is rated one of the most vulnerable of the freshmen against Democratic legislative powerhouse Joseph P. Merlino. Rep. Jim Courter (R) was moved into new territory, but won his primary and has no problems in November.

NORTH CAROLINA -- Rep. L.H. Fountain (D) decided not to seek reelection after the Justice Department insisted his district be redrawn to improve chances of a black candidate being nominated.Rep. Ike Andrews (D) was weakened by the changes made in Fountain's neighboring district and faces a stronger GOP challenge.

OHIO -- Republicans lost one seat when districting carved up the territory of the late Rep. John M. Ashbrook, who died while campaigning for the Senate nomination. They probably lost a second when Rep. Dennis E. Eckart (D) moved over to claim nomination in the district of retiring Rep. J. William Stanton (R), rather than go against Rep. Ronald M. Mottl (D) in an interparty primary, as first expected. The new lines improve GOP chances of beating freshman Rep. Bob Shamansky (D) with state Sen. John R. Kasich (R). But freshman Rep. Bob McEwen (R) has a more difficult district for his race with county prosecutor Lynn Alan Grimshaw (D).

PENNSYLVANIA -- The Republican districting plan forced two intraparty primaries among Democratic incumbents in May, with Rep. Joseph F. Smith losing to Rep. Thomas M. Foglietta and Rep. Don Bailey bowing to Rep. John P. Murtha. Rep. Robert W. Edgar (D) was weakened somewhat, but is still favored over Steve Joachim (R), his opponent. Republicans tried to build a safe district for Rep. Eugene V. Atkinson, who switched from the Democrats to the GOP last year, but he still faces a serious challenge from state Rep. Joseph P. Kolter (D).

SOUTH CAROLINA -- The political balance was not altered seriously, but freshman Rep. Thomas F. Hartnett (R) was strengthened slightly and freshman Rep. John L. Napier (R) waekened a bit by the division of their neighboring territory.

SOUTH DAKOTA -- The loss of one of the two House seats pits Rep. Thomas A. Daschle (D) against Rep. Clint Roberts (R), with Daschle leading narrowly in early polls.

TEXAS -- When all the dust had settled only two incumbents were significantly hurt by their new lines. Freshman Rep. Bill Patman (D) lost Nueces County (Corpus Christi) as a Democratic base and faces ex-Rep. Joe Wyatt Jr., who served in the last Congress as a Democrat but is running now as a Republican. Rep. Abraham Kazen Jr. (D) picks up Bexar County suburbs that tend Republican and has a potentially strong opponent in Bexar County commissioner Jeff Wentworth (R).

VIRGINIA -- The districting plan was essentially neutral, but Rep. Stan Parris (R), a narrow winner in 1980, was weakened sightly for his rematch with ex-Rep. Herbert E. Harris (D).

WASHINGTON -- The switch of the city of Everett (normally Democratic) from Rep. Al Swift (D) to Rep. Joel Pritchard (R) complicated life for both men, but neither is in serious jeopardy at this point.
